It is not intended to be a comprehensive resource. To complement the information in this data sheet, refer to the related section of the "dsPIC33/ PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 3.2 "Master Memory Organization" and Section 4.2 "Slave Memory Organization" in this data sheet for device-specific register and bit information. This document contains device-specific information for the dsPIC33CH128MP508 Digital Signal Controller (DSC) and Microcontroller (MCU) devices. dsPIC33CH128MP508 devices contain extensive Digital Signal Processor (DSP) functionality with a high-performance, 16-bit MCU architecture. Figure 1-2 shows a general block diagram of the cores and peripheral modules of the Master and Slave. Table 1-1 lists the functions of the various pins shown in the pinout diagrams. The Master core and Slave core can operate independently, and can be programmed and debugged separately during the application development. Both processor (Master and Slave) subsystems have their own interrupt controllers, clock generators, ICD, port logic, I/O MUXes and PPS. The device is equivalent to having two complete dsPIC(R) DSCs on a single die. The Master core will execute the code from Program Flash Memory (PFM) and the Slave core will operate from Program RAM Memory (PRAM). 2017-2018 Microchip Technology Inc. Once the code development is complete, the Master Flash will be programmed with the Master code, as well as the Slave code. After a Power-on Reset (POR), the Slave code from Master Flash will be loaded to the PRAM (program memory of the Slave) and the Slave can execute the code independently of the Master. The Master and Slave can communicate with each other using the Master Slave Interface (MSI) peripheral, and can exchange data between them. Figure 1-1 shows the block diagram of the device operation during a POR and the process of transferring the Slave code from the Master to Slave PRAM. The I/O ports are shared between the Master and Slave. Table 1 shows the number of peripherals and the shared peripherals that the Master and Slave own. There are Configuration bits in the Flash memory that specify the ownership (Master or Slave) of each device pin. The default (erased) state of the Flash assigns all of the device pins to the Master. The two cores (Master and Slave) can both be connected to debug tools, which support independent and simultaneous debugging. When the Slave core or Master core is debugged (non-Dual Debug mode), the S1MCLRx is not used. MCLR is used for programming and debugging both the Master core and the Slave core. S1MCLRx is only used when debugging both the cores at the same time. In normal operation, the "owner" of a device pin is responsible for full control of that pin; this includes both the digital and analog functionality. The pin owner's GPIO registers control all aspects of the I/O pad, including the ANSELx, CNPUx, CNPDx, ODCx registers and slew rate control. Note: Both the Master and Slave cores can monitor a pin as an input, regardless of pin ownership. Pin ownership is valid only for the output functionality of the port.

The following is a list of pin names which must always be connected: * All VDD and VSS pins (see Section 2.2 "Decoupling Capacitors") * All AVDD and AVSS pins regardless if ADC module is not used (see Section 2.2 "Decoupling Capacitors") * MCLR pin (see Section 2.3 "Master Clear (MCLR) Pin") * PGCx/PGDx pins used for In-Circuit Serial ProgrammingTM (ICSPTM) and debugging purposes (see Section 2.4 "ICSP Pins") * OSCI and OSCO pins when an external oscillator source is used (see Section 2.5 "External Oscillator Pins") 2017-2018 Microchip Technology Inc. 2.2 Decoupling Capacitors The use of decoupling capacitors on every pair of power supply pins, such as VDD, VSS, AVDD and AVSS is required. Consider the following criteria when using decoupling capacitors: * Value and type of capacitor: Recommendation of 0.1 F (100 nF), 10-20V. This capacitor should be a low-ESR and have resonance frequency in the range of 20 MHz and higher. It is recommended to use ceramic capacitors. * Placement on the printed circuit board: The decoupling capacitors should be placed as close to the pins as possible. It is recommended to place the capacitors on the same side of the board as the device. If space is constricted, the capacitor can be placed on another layer on the PCB using a via; however, ensure that the trace length from the pin to the capacitor is within one-quarter inch (6 mm) in length. * Handling high-frequency noise: If the board is experiencing high-frequency noise, above tens of MHz, add a second ceramic-type capacitor in parallel to the above described decoupling capacitor. The value of the second capacitor can be in the range of 0.01 F to 0.001 F. Place this second capacitor next to the primary decoupling capacitor. In high-speed circuit designs, consider implementing a decade pair of capacitances as close to the power and ground pins as possible. For example, 0.1 F in parallel with 0.001 F. * Maximizing performance: On the board layout from the power supply circuit, run the power and return traces to the decoupling capacitors first, and then to the device pins. This ensures that the decoupling capacitors are first in the power chain. Equally important is to keep the trace length between the capacitor and the power pins to a minimum, thereby reducing PCB track inductance.

The inductor impedance should be less than 1 and the inductor capacity greater than 10 mA. Where: F CNV f = -------------2 1 f = ---------------------- 2 LC (i.e., ADC Conversion Rate/2) 2 1 L = ---------------------- 2f C 2.2.1 The MCLR functions: provides two specific device * Device Reset * Device Programming and Debugging. For example, as shown in Figure 2-2, it is recommended that the capacitor, C, be isolated from the MCLR pin during programming and debugging operations. Note 1: There are the S1MCLR1, S1MCLR2 and S1MCLR3 pins and they are used for Slave debug during the dual debug process. Those pins do not reset the Slave core during normal operation. FIGURE 2-2: On boards with power traces running longer than six inches in length, it is suggested to use a bulk capacitor for integrated circuits, including DSCs, to supply a local power source. The value of the bulk capacitor should be determined based on the trace resistance that connects the power supply source to the device and the maximum current drawn by the device in the application. In other words, select the bulk capacitor so that it meets the acceptable voltage sag at the device. Typical values range from 4.7 F to 47 F. EXAMPLE OF MCLR PIN CONNECTIONS VDD R(1) BULK CAPACITORS DS70005319B-page 30 pin Place the components, as shown in Figure 2-2, within one-quarter inch (6 mm) from the MCLR pin. L1(1) Note 1: Master Clear (MCLR) Pin During device programming and debugging, the resistance and capacitance that can be added to the pin must be considered. Device programmers and debuggers drive the MCLR pin. Consequently, specific voltage levels (VIH and VIL) and fast signal transitions must not be adversely affected. Therefore, specific values of R and C will need to be adjusted based on the application and PCB requirements. MCLR VSS 2.3 R1(2) MCLR JP dsPIC33 C Note 1: R 10 k is recommended. A suggested starting value is 10 k. Ensure that the MCLR pin VIH and VIL specifications are met. 2: R1 470 will limit any current flowing into MCLR from the external capacitor, C, in the event of MCLR pin breakdown due to Electrostatic Discharge (ESD) or Electrical Overstress (EOS). Ensure that the MCLR pin VIH and VIL specifications are met. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 2.4 ICSP Pins The PGCx and PGDx pins are used for ICSP and debugging purposes. It is recommended to keep the trace length between the ICSP connector and the ICSP pins on the device as short as possible. If the ICSP connector is expected to experience an ESD event, a series resistor is recommended, with the value in the range of a few tens of Ohms, not to exceed 100 Ohms. Pull-up resistors, series diodes and capacitors on the PGCx and PGDx pins are not recommended as they will interfere with the programmer/debugger communications to the device. If such discrete components are an application requirement, they should be removed from the circuit during programming and debugging. Alternatively, refer to the AC/DC characteristics and timing requirements information in the respective device Flash programming specification for information on capacitive loading limits and pin Voltage Input High (VIH) and Voltage Input Low (VIL) requirements. Ensure that the "Communication Channel Select" (i.e., PGCx/PGDx pins) programmed into the device matches the physical connections for the ICSP to PICkitTM 3, MPLAB(R) ICD 3 or MPLAB REAL ICETM emulator. For more information on MPLAB ICD 2, MPLAB ICD 3 and REAL ICE emulator connection requirements, refer to the following documents that are available on the Microchip web site. * "Using MPLAB(R) ICD 3 In-Circuit Debugger" (poster) (DS51765) * "Development Tools Design Advisory" (DS51764) * "MPLAB(R) REAL ICETM In-Circuit Emulator User's Guide" (DS51616) * "Using MPLAB(R) REAL ICETM In-Circuit Emulator" (poster) (DS51749) 2017-2018 Microchip Technology Inc. 2.5 External Oscillator Pins Many DSCs have options for at least two oscillators: a high-frequency Primary Oscillator (POSC) and a low-frequency Secondary Oscillator (SOSC). For details, see Section 6.4.1 "Master Oscillator Control Registers". The oscillator circuit should be placed on the same side of the board as the device. Also, place the oscillator circuit close to the respective oscillator pins, not exceeding one-half inch (12 mm) distance between them. The load capacitors should be placed next to the oscillator itself, on the same side of the board. Use a grounded copper pour around the oscillator circuit to isolate them from surrounding circuits. The grounded copper pour should be routed directly to the MCU ground. Do not run any signal traces or power traces inside the ground pour. Also, if using a two-sided board, avoid any traces on the other side of the board where the crystal is placed. A suggested layout is shown in Figure 2-3. FIGURE 2-3: SUGGESTED PLACEMENT OF THE OSCILLATOR CIRCUIT Main Oscillator Guard Ring Guard Trace Oscillator Pins DS70005319B-page 31 dsPIC33CH128MP508 FAMILY 2.6 Oscillator Value Conditions on Device Start-up 2.8 If the PLL of the target device is enabled and configured for the device start-up oscillator, the maximum oscillator source frequency must be limited to a certain frequency (see Section 6.0 "Oscillator with High-Frequency PLL") to comply with device PLL start-up conditions. This means that if the external oscillator frequency is outside this range, the application must start up in the FRC mode first. The default PLL settings after a POR with an oscillator frequency outside this range will violate the device operating speed. Once the device powers up, the application firmware can initialize the PLL SFRs, CLKDIV and PLLFBD, to a suitable value, and then perform a clock switch to the Oscillator + PLL clock source. Note that clock switching must be enabled in the device Configuration Word. 2.7 Unused I/Os Unused I/O pins should be configured as outputs and driven to a logic low state. Targeted Applications * Power Factor Correction (PFC): - Interleaved PFC - Critical Conduction PFC - Bridgeless PFC * DC/DC Converters: - Buck, Boost, Forward, Flyback, Push-Pull - Half/Full-Bridge - Phase-Shift Full-Bridge - Resonant Converters * DC/AC: - Half/Full-Bridge Inverter - Resonant Inverter * Motor Control - BLDC - PMSM - SR - ACIM Examples of typical application connections are shown in Figure 2-4 through Figure 2-6.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "dsPIC33E Enhanced CPU" (DS70005158) in the "dsPIC33/ PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). There are two independent CPU cores in the dsPIC33CH128MP508 family. The Master and Slave cores are similar, except for the fact that the Slave core can run at a higher speed than the Master core. The Slave core fetches instructions from the PRAM and the Master core fetches the code from the Flash. The Master and Slave cores can run independently asynchronously, at the same speed or at a different speed. This section discusses the Master core. Note: All of the associated register names are the same on the Master, as well as on the Slave. The Slave code will be developed in a separate project in MPLAB(R) X IDE with the device selection, dsPIC33CH128MP508S1, where the S1 indicates the Slave device. 3.1.1 REGISTERS The dsPIC33CH128MP508 devices have sixteen, 16-bit Working registers in the programmer's model. Each of the Working registers can act as a Data, Address or Address Offset register. The 16th Working register (W15) operates as a Software Stack Pointer for interrupts and calls. In addition, the dsPIC33CH128MP508 devices include four Alternate Working register sets, which consist of W0 through W14. The Alternate Working registers can be made persistent to help reduce the saving and restoring of register content during Interrupt Service Routines (ISRs). The Alternate Working registers can be assigned to a specific Interrupt Priority Level (IPL1 through IPL7) by configuring the CTXTx<2:0> bits in the FALTREG Configuration register. The Alternate Working registers can also be accessed manually by using the CTXTSWP instruction. The CCTXI<2:0> and MCTXI<2:0> bits in the CTXTSTAT register can be used to identify the current, and most recent, manually selected Working register sets. 3.1.2 INSTRUCTION SET The instruction set for dsPIC33CH128MP508 devices has two classes of instructions: the MCU class of instructions and the DSP class of instructions. These two instruction classes are seamlessly integrated into the architecture and execute from a single execution unit. The instruction set includes many addressing modes and was designed for optimum C compiler efficiency. The dsPIC33CH128MP508 family CPU has a 16-bit (data) modified Harvard architecture with an enhanced instruction set, including significant support for Digital Signal Processing (DSP). The CPU has a 24-bit instruction word with a variable length opcode field. The Program Counter (PC) is 23 bits wide and addresses up to 4M x 24 bits of user program memory space. An instruction prefetch mechanism helps maintain throughput and provides predictable execution. Most instructions execute in a single-cycle effective execution rate, with the exception of instructions that change the program flow, the double-word move (MOV.D) instruction, PSV accesses and the table instructions. Overhead-free program loop constructs are supported using the DO and REPEAT instructions, both of which are interruptible at any point. 2017-2018 Microchip Technology Inc. DS70005319B-page 35 dsPIC33CH128MP508 FAMILY 3.1.3 DATA SPACE ADDRESSING The base Data Space (DS) can be addressed as up to 4K words or 8 Kbytes, and is split into two blocks, referred to as X and Y data memory. Each memory block has its own independent Address Generation Unit (AGU). The MCU class of instructions operates solely through the X memory AGU, which accesses the entire memory map as one linear Data Space. Certain DSP instructions operate through the X and Y AGUs to support dual operand reads, which splits the data address space into two parts. The X and Y Data Space boundary is device-specific. The upper 32 Kbytes of the Data Space memory map can optionally be mapped into Program Space (PS) at any 16K program word boundary. The program-to-Data Space mapping feature, known as Program Space Visibility (PSV), lets any instruction access Program Space as if it were Data Space. Refer to "Data Memory" (DS70595) in the "dsPIC33/PIC24 Family Reference Manual" for more details on PSV and table accesses. 3.1.4 ADDRESSING MODES The CPU supports these addressing modes: * * * * * * Inherent (no operand) Relative Literal Memory Direct Register Direct Register Indirect Each instruction is associated with a predefined addressing mode group, depending upon its functional requirements. As many as six addressing modes are supported for each instruction. On dsPIC33CH128MP508 family devices, overheadfree circular buffers (Modulo Addressing) are supported in both X and Y address spaces. The Modulo Addressing removes the software boundary checking overhead for DSP algorithms. The X AGU Circular Addressing can be used with any of the MCU class of instructions. The X AGU also supports BitReversed Addressing to greatly simplify input or output data re-ordering for radix-2 FFT algorithms.

Unless otherwise mentioned, arithmetic operations are two's complement in nature. Depending on the operation, the ALU can affect the values of the Carry (C), Zero (Z), Negative (N), Overflow (OV) and Digit Carry (DC) Status bits in the SR register. The C and DC Status bits operate as Borrow and Digit Borrow bits, respectively, for subtraction operations. The ALU can perform 8-bit or 16-bit operations, depending on the mode of the instruction that is used. Data for the ALU operation can come from the W register array or data memory, depending on the addressing mode of the instruction. Likewise, output data from the ALU can be written to the W register array or a data memory location. Refer to the "16-Bit MCU and DSC Programmer's Reference Manual" (DS70000157) for information on the SR bits affected by each instruction. The core CPU incorporates hardware support for both multiplication and division. This includes a dedicated hardware multiplier and support hardware for 16-bit divisor division. 3.1.8.1 Multiplier Using the high-speed, 17-bit x 17-bit multiplier, the ALU supports unsigned, signed or mixed-sign operation in several MCU multiplication modes: * * * * * * * 16-bit x 16-bit signed 16-bit x 16-bit unsigned 16-bit signed x 5-bit (literal) unsigned 16-bit signed x 16-bit unsigned 16-bit unsigned x 5-bit (literal) unsigned 16-bit unsigned x 16-bit signed 8-bit unsigned x 8-bit unsigned 3.1.8.2 Divider The divide block supports 32-bit/16-bit and 16-bit/16-bit signed and unsigned integer divide operations with the following data sizes: * * * * 3.1.9 DSP ENGINE The DSP engine consists of a high-speed 17-bit x 17-bit multiplier, a 40-bit barrel shifter and a 40-bit adder/ subtracter (with two target accumulators, round and saturation logic). The DSP engine can also perform inherent accumulatorto-accumulator operations that require no additional data. These instructions are, ADD, SUB, NEG, MIN and MAX. The DSP engine has options selected through bits in the CPU Core Control register (CORCON), as listed below: * Fractional or integer DSP multiply (IF) * Signed, unsigned or mixed-sign DSP multiply (USx) * Conventional or convergent rounding (RND) * Automatic saturation on/off for ACCA (SATA) * Automatic saturation on/off for ACCB (SATB) * Automatic saturation on/off for writes to data memory (SATDW) * Accumulator Saturation mode selection (ACCSAT) TABLE 3-2: Instruction CLR DSP INSTRUCTIONS SUMMARY Algebraic Operation ACC Write-Back Yes A=0 2 ED A = (x - y) No EDAC A = A + (x - y)2 No MAC A = A + (x * y) Yes MAC A = A + x2 No MOVSAC No change in A Yes MPY A=x*y No 2 No MPY A=x MPY.N A=-x*y No MSC A=A-x*y Yes 32-bit signed/16-bit signed divide 32-bit unsigned/16-bit unsigned divide 16-bit signed/16-bit signed divide 16-bit unsigned/16-bit unsigned divide The 16-bit signed and unsigned DIV instructions can specify any W register for both the 16-bit divisor (Wn) and any W register (aligned) pair (W(m + 1):Wm) for the 32-bit dividend. The divide algorithm takes one cycle per bit of divisor, so both 32-bit/16-bit and 16-bit/ 16-bit instructions take the same number of cycles to execute. There are additional instructions: DIV2 and DIVF2. Divide instructions will complete in six cycles. 2017-2018 Microchip Technology Inc.

The space is addressable by a 24-bit value derived either from the 23-bit PC during program execution, or from table operation or Data Space remapping, as described in Section 3.2.9 "Interfacing Program and Data Memory Spaces". This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "dsPIC33E/PIC24E Program Memory" (DS70000613) in the "dsPIC33/ PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). User application access to the program memory space is restricted to the lower half of the address range (0x000000 to 0x7FFFFF). The exception is the use of TBLRD operations, which use TBLPAG<7> to permit access to calibration data and Device ID sections of the configuration memory space. The dsPIC33CH128MP508 family architecture features separate program and data memory spaces, and buses. This architecture also allows the direct access of program memory from the Data Space (DS) during code execution. The program memory maps for the Master dsPIC33CHXXXMPX08 device are shown in Figure 3-3 and Figure 3-4.

DS70005319B-page 47 dsPIC33CH128MP508 FAMILY 3.2.1.1 Program Memory Organization 3.2.1.2 The program memory space is organized in wordaddressable blocks. Although it is treated as 24 bits wide, it is more appropriate to think of each address of the program memory as a lower and upper word, with the upper byte of the upper word being unimplemented. The lower word always has an even address, while the upper word has an odd address (Figure 3-5). All dsPIC33CH128MP508 family devices reserve the addresses between 0x000000 and 0x000200 for hardcoded program execution vectors. A hardware Reset vector is provided to redirect code execution from the default value of the PC on device Reset to the actual start of code. A GOTO instruction is programmed by the user application at address, 0x000000, of Flash memory, with the actual address for the start of code at address, 0x000002, of Flash memory. Program memory addresses are always word-aligned on the lower word, and addresses are incremented or decremented, by two, during code execution. This arrangement provides compatibility with data memory space addressing and makes data in the program memory space accessible. FIGURE 3-5: A more detailed discussion of the Interrupt Vector Tables (IVTs) is provided in Section 3.5 "Master Interrupt Controller".

The UDID cannot be erased by a bulk erase command or any other user-accessible means. This feature allows for manufacturing traceability of Microchip Technology devices in applications where this is a requirement. It may also be used by the application manufacturer for any number of things that may require unique identification, such as: * Tracking the device * Unique serial number * Unique security key Instruction Width The UDID is stored in five read-only locations, located between 0x801200 and 0x801208 in the device configuration space. Table 3-3 lists the addresses of the identifier words and shows their contents TABLE 3-3: UDID ADDRESSES UDID Address Description UDID1 0x801200 UDID Word 1 UDID2 0x801202 UDID Word 2 UDID3 0x801204 UDID Word 3 UDID4 0x801206 UDID Word 4 UDID5 0x801208 UDID Word 5 The UDID comprises five 24-bit program words. When taken together, these fields form a unique 120-bit identifier.

The Data Space is accessed using separate Address Generation Units (AGUs) for read and write operations. The data memory map is shown in Figure 3-6. All Effective Addresses (EAs) in the data memory space are 16 bits wide and point to bytes within the Data Space. This arrangement gives a base Data Space address range of 64 Kbytes or 32K words. The lower half of the data memory space (i.e., when EA<15> = 0) is used for implemented memory addresses, while the upper half (EA<15> = 1) is reserved for the Program Space Visibility (PSV). The dsPIC33CH128MP508 family devices implement up to 16 Kbytes of data memory. If an EA points to a location outside of this area, an all-zero word or byte is returned. 3.2.3.1 Data Space Width The data memory space is organized in byteaddressable, 16-bit wide blocks. Data is aligned in data memory and registers as 16-bit words, but all Data Space EAs resolve to bytes. The Least Significant Bytes (LSBs) of each word have even addresses, while the Most Significant Bytes (MSBs) have odd addresses. 3.2.3.2 Data Memory Organization and Alignment To maintain backward compatibility with PIC(R) MCU devices and improve Data Space memory usage efficiency, the dsPIC33CH128MP508 family instruction set supports both word and byte operations. As a consequence of byte accessibility, all Effective Address calculations are internally scaled to step through wordaligned memory. For example, the core recognizes that Post-Modified Register Indirect Addressing mode [Ws++] results in a value of Ws + 1 for byte operations and Ws + 2 for word operations. A data byte read, reads the complete word that contains the byte, using the LSb of any EA to determine which byte to select. The selected byte is placed onto the LSB of the data path. That is, data memory and registers are organized as two parallel, byte-wide entities with shared (word) address decode, but separate write lines. Data byte writes only write to the corresponding side of the array or register that matches the byte address. 2017-2018 Microchip Technology Inc. All word accesses must be aligned to an even address. Misaligned word data fetches are not supported, so care must be taken when mixing byte and word operations, or translating from 8-bit MCU code. If a misaligned read or write is attempted, an address error trap is generated. If the error occurred on a read, the instruction underway is completed. If the error occurred on a write, the instruction is executed but the write does not occur. In either case, a trap is then executed, allowing the system and/or user application to examine the machine state prior to execution of the address Fault. All byte loads into any W register are loaded into the LSB; the MSB is not modified. A Sign-Extend (SE) instruction is provided to allow user applications to translate 8-bit signed data to 16-bit signed values. Alternatively, for 16-bit unsigned data, user applications can clear the MSB of any W register by executing a Zero-Extend (ZE) instruction on the appropriate address. 3.2.3.3 SFR Space The first 4 Kbytes of the Near Data Space, from 0x0000 to 0x0FFF, is primarily occupied by Special Function Registers (SFRs). These are used by the dsPIC33CH128MP508 family core and peripheral modules for controlling the operation of the device. SFRs are distributed among the modules that they control and are generally grouped together by module. Much of the SFR space contains unused addresses; these are read as `0'. Note: 3.2.3.4 The actual set of peripheral features and interrupts varies by the device. Refer to the corresponding device tables and pinout diagrams for device-specific information. Near Data Space The 8-Kbyte area, between 0x0000 and 0x1FFF, is referred to as the Near Data Space. Locations in this space are directly addressable through a 13-bit absolute address field within all memory direct instructions. Additionally, the whole Data Space is addressable using MOV instructions, which support Memory Direct Addressing mode with a 16-bit address field, or by using Indirect Addressing mode using a Working register as an Address Pointer.

DS70005319B-page 50 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 3.2.3.5 X and Y Data Spaces The dsPIC33CH128MP508 family core has two Data Spaces, X and Y. These Data Spaces can be considered either separate (for some DSP instructions) or as one unified linear address range (for MCU instructions). The Data Spaces are accessed using two Address Generation Units (AGUs) and separate data paths. This feature allows certain instructions to concurrently fetch two words from RAM, thereby enabling efficient execution of DSP algorithms, such as Finite Impulse Response (FIR) filtering and Fast Fourier Transform (FFT). The X Data Space is used by all instructions and supports all addressing modes. X Data Space has separate read and write data buses. The X read data bus is the read data path for all instructions that view Data Space as combined X and Y address space. It is also the X data prefetch path for the dual operand DSP instructions (MAC class). The Y Data Space is used in concert with the X Data Space by the MAC class of instructions (CLR, ED, EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide two concurrent data read paths. 2017-2018 Microchip Technology Inc. Both the X and Y Data Spaces support Modulo Addressing mode for all instructions, subject to addressing mode restrictions. Bit-Reversed Addressing mode is only supported for writes to X Data Space. All data memory writes, including in DSP instructions, view Data Space as combined X and Y address space. The boundary between the X and Y Data Spaces is device-dependent and is not user-programmable. 3.2.4 MEMORY RESOURCES Many useful resources are provided on the main product page of the Microchip web site for the devices listed in this data sheet.

DS70005319B-page 65 dsPIC33CH128MP508 FAMILY 3.2.5.1 Paged Memory Scheme The paged memory scheme provides access to multiple 32-Kbyte windows in the PSV memory. The Data Space Read Page (DSRPAG) register, in combination with the upper half of the Data Space address, can provide up to 8 Mbytes of PSV address space. The paged data memory space is shown in Figure 3-8. The dsPIC33CH128MP508 architecture extends the available Data Space through a paging scheme, which allows the available Data Space to be accessed using MOV instructions in a linear fashion for pre- and post-modified Effective Addresses (EAs). The upper half of the base Data Space address is used in conjunction with the Data Space Read Page (DSRPAG) register to form the Program Space Visibility (PSV) address. The Program Space (PS) can be accessed with a DSRPAG of 0x200 or greater. Only reads from PS are supported using the DSRPAG. The Data Space Read Page (DSRPAG) register is located in the SFR space. Construction of the PSV address is shown in Figure 3-7. When DSRPAG<9> = 1 and the base address bit, EA<15> = 1, the DSRPAG<8:0> bits are concatenated onto EA<14:0> to form the 24-bit PSV read address.

An overflow or underflow of the EA in the PSV pages can occur at the page boundaries when: * The initial address, prior to modification, addresses the PSV page * The EA calculation uses Pre- or Post-Modified Register Indirect Addressing; however, this does not include Register Offset Addressing In general, when an overflow is detected, the DSRPAG register is incremented and the EA<15> bit is set to keep the base address within the PSV window. When an underflow is detected, the DSRPAG register is decremented and the EA<15> bit is set to keep the base TABLE 3-19: O, Read [++Wn] or [Wn++] U, Read U, Read U, Read [--Wn] or [Wn--] Legend: Note 1: 2: 3: 4: Exceptions to the operation described above arise when entering and exiting the boundaries of Page 0 and PSV spaces.

An EDS access, with DSRPAG = 0x000, will generate an address error trap. Only reads from PS are supported using DSRPAG. Pseudolinear Addressing is not supported for large offsets. DS70005319B-page 68 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 3.2.5.2 Extended X Data Space The lower portion of the base address space range, between 0x0000 and 0x7FFF, is always accessible, regardless of the contents of the Data Space Read Page register. It is indirectly addressable through the register indirect instructions. It can be regarded as being located in the default EDS Page 0 (i.e., EDS address range of 0x000000 to 0x007FFF with the base address bit, EA<15> = 0, for this address range). However, Page 0 cannot be accessed through the upper 32 Kbytes, 0x8000 to 0xFFFF, of base Data Space in combination with DSRPAG = 0x00. Consequently, DSRPAG is initialized to 0x001 at Reset. Note 1: DSRPAG should not be used to access Page 0. An EDS access with DSRPAG set to 0x000 will generate an address error trap. When the PC is pushed onto the stack, PC<15:0> are pushed onto the first available stack word, then PC<22:16> are pushed into the second available stack location. For a PC push during any CALL instruction, the MSB of the PC is zero-extended before the push, as shown in Figure 3-9. During exception processing, the MSB of the PC is concatenated with the lower eight bits of the CPU STATUS Register, SR. This allows the contents of SRL to be preserved automatically during interrupt processing. Note 1: To maintain system Stack Pointer (W15) coherency, W15 is never subject to (EDS) paging, and is therefore, restricted to an address range of 0x0000 to 0xFFFF. The same applies to the W14 when used as a Stack Frame Pointer (SFA = 1). 2: As the stack can be placed in, and can access X and Y spaces, care must be taken regarding its use, particularly with regard to local automatic variables in a C development environment 2: Clearing the DSRPAG in software has no effect. 3.2.5.3 Software Stack The W15 register serves as a dedicated Software Stack Pointer (SSP), and is automatically modified by exception processing, subroutine calls and returns; however, W15 can be referenced by any instruction in the same manner as all other W registers. This simplifies reading, writing and manipulating the Stack Pointer (for example, creating stack frames). Note: To protect against misaligned stack accesses, W15<0> is fixed to `0' by the hardware. FIGURE 3-9: 0x0000 CALL STACK FRAME 15 0 CALL SUBR Stack Grows Toward Higher Address The remaining PSV pages are only accessible using the DSRPAG register in combination with the upper 32 Kbytes, 0x8000 to 0xFFFF, of the base address, where the base address bit, EA<15> = 1. PC<15:1> W15 (before CALL) b`000000000' PC<22:16> <Free Word> W15 (after CALL) W15 is initialized to 0x1000 during all Resets. This address ensures that the SSP points to valid RAM in all dsPIC33CH128MP508 devices and permits stack availability for non-maskable trap exceptions. These can occur before the SSP is initialized by the user software. You can reprogram the SSP during initialization to any location within Data Space. The Software Stack Pointer always points to the first available free word and fills the software stack, working from lower toward higher addresses. Figure 3-9 illustrates how it pre-decrements for a stack pop (read) and post-increments for a stack push (writes). 2017-2018 Microchip Technology Inc. DS70005319B-page 69 dsPIC33CH128MP508 FAMILY 3.2.6 INSTRUCTION ADDRESSING MODES The addressing modes shown in Table 3-20 form the basis of the addressing modes optimized to support the specific features of individual instructions. The addressing modes provided in the MAC class of instructions differ from those in the other instruction types. 3.2.6.1 File Register Instructions Most file register instructions use a 13-bit address field (f) to directly address data present in the first 8192 bytes of data memory (Near Data Space). Most file register instructions employ a Working register, W0, which is denoted as WREG in these instructions. The destination is typically either the same file register or WREG (with the exception of the MUL instruction), which writes the result to a register or register pair. The MOV instruction allows additional flexibility and can access the entire Data Space. TABLE 3-20: 3.2.6.2 MCU Instructions The three-operand MCU instructions are of the form: Operand 3 = Operand 1 <function> Operand 2 where Operand 1 is always a Working register (that is, the addressing mode can only be Register Direct), which is referred to as Wb. Operand 2 can be a W register fetched from data memory or a 5-bit literal. The result location can either be a W register or a data memory location. The following addressing modes are supported by MCU instructions: * * * * * Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified 5-Bit or 10-Bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions can support different subsets of these addressing modes. FUNDAMENTAL ADDRESSING MODES SUPPORTED Addressing Mode File Register Direct Description The address of the file register is specified explicitly. Register Direct The contents of a register are accessed directly. Register Indirect The contents of Wn form the Effective Address (EA). Register Indirect Post-Modified The contents of Wn form the EA. Wn is post-modified (incremented or decremented) by a constant value. Register Indirect Pre-Modified Wn is pre-modified (incremented or decremented) by a signed constant value to form the EA. Register Indirect with Register Offset The sum of Wn and Wb forms the EA. (Register Indexed) Register Indirect with Literal Offset DS70005319B-page 70 The sum of Wn and a literal forms the EA. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 3.2.6.3 Move and Accumulator Instructions Move instructions, and the DSP accumulator class of instructions, provide a greater degree of addressing flexibility than other instructions. In addition to the addressing modes supported by most MCU instructions, move and accumulator instructions also support Register Indirect with Register Offset Addressing mode, also referred to as Register Indexed mode. Note: For the MOV instructions, the addressing mode specified in the instruction can differ for the source and destination EA. However, the 4-bit Wb (Register Offset) field is shared by both source and destination (but typically only used by one). 3.2.6.4 The dual source operand DSP instructions (CLR, ED, EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), also referred to as MAC instructions, use a simplified set of addressing modes to allow the user application to effectively manipulate the Data Pointers through register indirect tables. The two-source operand prefetch registers must be members of the set {W8, W9, W10, W11}. For data reads, W8 and W9 are always directed to the X RAGU, and W10 and W11 are always directed to the Y AGU. The Effective Addresses generated (before and after modification) must therefore, be valid addresses within X Data Space for W8 and W9, and Y Data Space for W10 and W11. In summary, the following addressing modes are supported by move and accumulator instructions: * * * * * * * * Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified Register Indirect with Register Offset (Indexed) Register Indirect with Literal Offset 8-Bit Literal 16-Bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions may support different subsets of these addressing modes. 2017-2018 Microchip Technology Inc. MAC Instructions Note: Register Indirect with Register Offset Addressing mode is available only for W9 (in X space) and W11 (in Y space). In summary, the following addressing modes are supported by the MAC class of instructions: * * * * * Register Indirect Register Indirect Post-Modified by 2 Register Indirect Post-Modified by 4 Register Indirect Post-Modified by 6 Register Indirect with Register Offset (Indexed) 3.2.6.5 Other Instructions Besides the addressing modes outlined previously, some instructions use literal constants of various sizes. For example, BRA (branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the DISI instruction uses a 14-bit unsigned literal field. In some instructions, such as ULNK, the source of an operand or result is implied by the opcode itself. Certain operations, such as a NOP, do not have any operands. DS70005319B-page 71 dsPIC33CH128MP508 FAMILY 3.2.7 MODULO ADDRESSING 3.2.7.1 Modulo Addressing mode is a method of providing an automated means to support circular data buffers using hardware. The objective is to remove the need for software to perform data address boundary checks when executing tightly looped code, as is typical in many DSP algorithms. Start and End Address The Modulo Addressing scheme requires that a starting and ending address be specified and loaded into the 16-bit Modulo Buffer Address registers: XMODSRT, XMODEND, YMODSRT and YMODEND (see Table 3-4). Note: Y space Modulo Addressing EA calculations assume word-sized data (LSb of every EA is always clear). Modulo Addressing can operate in either Data or Program Space (since the Data Pointer mechanism is essentially the same for both). One circular buffer can be supported in each of the X (which also provides the pointers into Program Space) and Y Data Spaces. Modulo Addressing can operate on any W Register Pointer. However, it is not advisable to use W14 or W15 for Modulo Addressing since these two registers are used as the Stack Frame Pointer and Stack Pointer, respectively. The length of a circular buffer is not directly specified. It is determined by the difference between the corresponding start and end addresses. The maximum possible length of the circular buffer is 32K words (64 Kbytes). In general, any particular circular buffer can be configured to operate in only one direction, as there are certain restrictions on the buffer start address (for incrementing buffers) or end address (for decrementing buffers), based upon the direction of the buffer. The Modulo and Bit-Reversed Addressing Control register, MODCON<15:0>, contains enable flags, as well as a W register field to specify the W Address registers. The XWM and YWM fields select the registers that operate with Modulo Addressing: The only exception to the usage restrictions is for buffers that have a power-of-two length. As these buffers satisfy the start and end address criteria, they can operate in a Bidirectional mode (that is, address boundary checks are performed on both the lower and upper address boundaries). * If XWM = 1111, X RAGU and X WAGU Modulo Addressing is disabled * If YWM = 1111, Y AGU Modulo Addressing is disabled 3.2.7.2 W Address Register Selection The X Address Space Pointer W (XWM) register, to which Modulo Addressing is to be applied, is stored in MODCON<3:0> (see Table 3.2.1). Modulo Addressing is enabled for X Data Space when XWM is set to any value other than `1111' and the XMODEN bit is set (MODCON<15>). The Y Address Space Pointer W (YWM) register, to which Modulo Addressing is to be applied, is stored in MODCON<7:4>. Modulo Addressing is enabled for Y Data Space when YWM is set to any value other than `1111' and the YMODEN bit (MODCON<14>) is set.

Address boundaries check for addresses equal to: * The upper boundary addresses for incrementing buffers * The lower boundary addresses for decrementing buffers It is important to realize that the address boundaries check for addresses less than, or greater than, the upper (for incrementing buffers) and lower (for decrementing buffers) boundary addresses (not just equal to). Address changes can, therefore, jump beyond boundaries and still be adjusted correctly. Note: 3.2.8 The modulo corrected Effective Address is written back to the register only when Pre-Modify or Post-Modify Addressing mode is used to compute the Effective Address. When an address offset (such as [W7 + W2]) is used, Modulo Addressing correction is performed, but the contents of the register remain unchanged. BIT-REVERSED ADDRESSING Bit-Reversed Addressing mode is intended to simplify data reordering for radix-2 FFT algorithms. It is supported by the X AGU for data writes only. The modifier, which can be a constant value or register contents, is regarded as having its bit order reversed. The address source and destination are kept in normal order. Thus, the only operand requiring reversal is the modifier. 3.2.8.1 Bit-Reversed Addressing Implementation Bit-Reversed Addressing mode is enabled in any of these situations: * BWMx bits (W register selection) in the MODCON register are any value other than `1111' (the stack cannot be accessed using Bit-Reversed Addressing) * The BREN bit is set in the XBREV register * The addressing mode used is Register Indirect with Pre-Increment or Post-Increment If the length of a bit-reversed buffer is M = 2N bytes, the last `N' bits of the data buffer start address must be zeros. XB<14:0> is the Bit-Reversed Addressing modifier, or `pivot point', which is typically a constant. In the case of an FFT computation, its value is equal to half of the FFT data buffer size. Note: All bit-reversed EA calculations assume word-sized data (LSb of every EA is always clear). The XB value is scaled accordingly to generate compatible (byte) addresses. When enabled, Bit-Reversed Addressing is executed only for Register Indirect with Pre-Increment or PostIncrement Addressing and word-sized data writes. It does not function for any other addressing mode or for byte-sized data and normal addresses are generated instead. When Bit-Reversed Addressing is active, the W Address Pointer is always added to the address modifier (XB) and the offset associated with the Register Indirect Addressing mode is ignored. In addition, as word-sized data is a requirement, the LSb of the EA is ignored (and always clear). Note: Modulo Addressing and Bit-Reversed Addressing can be enabled simultaneously using the same W register, but BitReversed Addressing operation will always take precedence for data writes when enabled. If Bit-Reversed Addressing has already been enabled by setting the BREN (XBREV<15>) bit, a write to the XBREV register should not be immediately followed by an indirect read operation using the W register that has been designated as the Bit-Reversed Pointer. 2017-2018 Microchip Technology Inc.

This capability makes the method ideal for accessing data tables that need to be updated periodically. It also allows access to all bytes of the program word. The remapping method allows an application to access a large block of data on a read-only basis, which is ideal for look-ups from a large table of static data. The application can only access the least significant word of the program word. The dsPIC33CH128MP508 family architecture uses a 24-bit wide Program Space (PS) and a 16-bit wide Data Space (DS). The architecture is also a modified Harvard scheme, meaning that data can also be present in the Program Space. To use this data successfully, it must be accessed in a way that preserves the alignment of information in both spaces. Aside from normal execution, the architecture of the dsPIC33CH128MP508 family devices provides two methods by which Program Space can be accessed during operation: * Using table instructions to access individual bytes or words anywhere in the Program Space * Remapping a portion of the Program Space into the Data Space (Program Space Visibility) TABLE 3-22: PROGRAM SPACE ADDRESS CONSTRUCTION Program Space Address Access Space Access Type <23> <22:16> Instruction Access (Code Execution) User TBLRD/TBLWT (Byte/Word Read/Write) User TBLPAG<7:0> Configuration TBLPAG<7:0> <15> 0xxx xxxx xxxx 0xxx xxxx <0> 0 xxxx xxxx xxx0 Data EA<15:0> xxxx xxxx xxxx xxxx 1xxx xxxx FIGURE 3-12: <14:1> PC<22:1> 0 Data EA<15:0> xxxx xxxx xxxx xxxx DATA ACCESS FROM PROGRAM SPACE ADDRESS GENERATION Program Counter(1) Program Counter 0 0 23 Bits EA Table Operations(2) 1/0 1/0 TBLPAG 8 Bits 16 Bits 24 Bits User/Configuration Space Select Note 1: 2: Byte Select The Least Significant bit (LSb) of Program Space addresses is always fixed as `0' to maintain word alignment of data in the Program and Data Spaces. Table operations are not required to be word-aligned. Table Read operations are permitted in the configuration memory space. 2017-2018 Microchip Technology Inc. DS70005319B-page 75 dsPIC33CH128MP508 FAMILY 3.2.9.1 Data Access from Program Memory Using Table Instructions The TBLRDL and TBLWTL instructions offer a direct method of reading or writing the lower word of any address within the Program Space without going through Data Space. The TBLRDH and TBLWTH instructions are the only method to read or write the upper 8 bits of a Program Space word as data. The PC is incremented by two for each successive 24-bit program word. This allows program memory addresses to directly map to Data Space addresses. Program memory can thus be regarded as two 16-bit wide word address spaces, residing side by side, each with the same address range. TBLRDL and TBLWTL access the space that contains the least significant data word. TBLRDH and TBLWTH access the space that contains the upper data byte. Two table instructions are provided to move byte or word-sized (16-bit) data to and from Program Space. Both function as either byte or word operations. * TBLRDL (Table Read Low): - In Word mode, this instruction maps the lower word of the Program Space location (P<15:0>) to a data address (D<15:0>) - In Byte mode, either the upper or lower byte of the lower program word is mapped to the lower byte of a data address. The upper byte is selected when Byte Select is `1'; the lower byte is selected when it is `0'. FIGURE 3-13: * TBLRDH (Table Read High): - In Word mode, this instruction maps the entire upper word of a program address (P<23:16>) to a data address. The `phantom' byte (D<15:8>) is always `0'. - In Byte mode, this instruction maps the upper or lower byte of the program word to D<7:0> of the data address in the TBLRDL instruction. The data is always `0' when the upper `phantom' byte is selected (Byte Select = 1). In a similar fashion, two table instructions, TBLWTH and TBLWTL, are used to write individual bytes or words to a Program Space address. The details of their operation are explained in Section 3.3 "Master Flash Program Memory". For all table operations, the area of program memory space to be accessed is determined by the Table Page register (TBLPAG). TBLPAG covers the entire program memory space of the device, including user application and configuration spaces. When TBLPAG<7> = 0, the table page is located in the user memory space. When TBLPAG<7> = 1, the page is located in configuration space.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Flash Programming" (DS70609) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: This section refers to the "Dual Partition Flash Program Memory" (DS70005156) in the "dsPIC33/PIC24 Family Reference Manual", but the Dual Partition is not implemented in the Master Flash. The dsPIC33CH128MP508 family devices contain internal Flash program memory for storing and executing application code. The memory is readable, writable and erasable during normal operation over the entire VDD range. Flash memory can be programmed in three ways: * In-Circuit Serial ProgrammingTM (ICSPTM) programming capability * Enhanced In-Circuit Serial Programming (Enhanced ICSP) * Run-Time Self-Programming (RTSP) ICSP allows for a dsPIC33CH128MP508 family device to be serially programmed while in the end application circuit. This is done with a Programming Clock and Programming Data (PGCx/PGDx) line, and three other lines for power (VDD), ground (VSS) and Master Clear (MCLR). This allows customers to manufacture boards with unprogrammed devices and then program the device just before shipping the product. This also allows the most recent firmware or a custom firmware to be programmed. RTSP allows the Master Flash user application code to update itself during run time. The feature is capable of writing a single program memory word (two instructions) or an entire row as needed. 3.3.1 FLASH PROGRAMMING OPERATIONS For ICSP and RTSP programming of the Master Flash, TBLWTL and TBLWTH instructions are used to write to the NVM write latches. An NVM write operation then writes the contents of both latches to the Flash, starting at the address defined by the contents of TBLPAG, and the NVMADR and NVMADRU registers. Programmers can program two adjacent words (24 bits x 2) of Program Flash Memory at a time on every other word address boundary (0x000002, 0x000006, 0x00000A, etc.). To do this, it is necessary to erase the page that contains the desired address of the location the user wants to change. For protection against accidental operations, the write initiate sequence for NVMKEY must be used to allow any erase or program operation to proceed. After the programming command has been executed, the user application must wait for the programming time until programming is complete. Regardless of the method used to program the Flash, a few basic requirements should be met: * A full 48-bit double instruction word should always be programmed to a Flash location. Either instruction may simply be a NOP to fulfill this requirement. This ensures a valid ECC value is generated for each pair of instructions written. * Assuming the above step is followed, the last 24-bit location in implemented program space should never be executed. The penultimate instruction must contain a program flow change instruction, such as a RETURN or BRA instruction. Enhanced In-Circuit Serial Programming uses an on-board bootloader, known as the Program Executive, to manage the programming process. Using an SPI data frame format, the Program Executive can erase, program and verify program memory. For more information on Enhanced ICSP, see the device programming specification. 2017-2018 Microchip Technology Inc.

The basic sequence for RTSP programming is to first load two 24-bit instructions into the NVM write latches found in configuration memory space. Refer to Figure 3-3 EXAMPLE 3-1: through Figure 3-4 for write latch addresses. Then, the WR bit in the NVMCON register is set to initiate the write process. The processor stalls (waits) until the programming operation is finished. The WR bit is automatically cleared when the operation is finished. Double instruction word writes are performed by manually loading both write latches, using TBLWTL and TBLWTH instructions, and then initiating the NVM write while the NVMOPx bits are set to `0x1'. The program space destination address is defined by the NVMADR/U registers.

DS70005319B-page 79 dsPIC33CH128MP508 FAMILY Row programming is performed by first loading 128 instructions into data RAM and then loading the address of the first instruction in that row into the NVMSRCADRL/H registers. Once the write has been initiated, the device will automatically load two instructions into the write latches and write them to the program space destination address defined by the NVMADR/U registers. The operation will increment the NVMSRCADRL/H and the NVMADR/U registers until all double instruction words have been programmed. The RPDF bit (NVMCON<9>) selects the format of the stored data in RAM to be either compressed or uncompressed. See Figure 3-15 for data formatting. Compressed data helps to reduce the amount of required RAM by using the upper byte of the second word for the MSB of the second instruction. All erase and program operations may optionally use the NVM interrupt to signal the successful completion of the operation.

ECC can determine the presence of single bit errors in program data, including which bit is in error, and correct the data automatically without user intervention. ECC cannot be disabled. When data is written to program memory, ECC generates a 7-bit Hamming code parity value for every two (24-bit) instruction words. The data is stored in blocks of 48 data bits and 7 parity bits; parity data is not memorymapped and is inaccessible. When the data is read back, the ECC calculates the parity on it and compares it to the previously stored parity value. If a parity mismatch occurs, there are two possible outcomes: * Single bit error has occurred and has been automatically corrected on readback. * Double-bit error has occurred and the read data is not changed. Single bit error occurrence can be identified by the state of the ECCSBEIF (IFS0<13>) bit. An interrupt can be generated when the corresponding interrupt enable bit is set, ECCSBEIE (IEC0<13>). The ECCSTATL register contains the parity information for single bit errors. The SECOUT<7:0> bit field contains the expected calculated SEC parity and SECIN<7:0> bits contain the actual value from a Flash read operation. The SECSYNDx bits (ECCSTATH<7:0>) indicate the bit position of the single bit error within the 48-bit pair of instruction words. When no error is present, SECINx equals SECOUTx and SECSYNDx is zero. Double-bit errors result in a generic hard trap. The ECCDBE bit (INTCON4<1>) will be set to identify the source of the hard trap. If no Interrupt Service Routine is implemented for the hard trap, a device Reset will also occur. The ECCSTATH register contains double-bit error status information. The DEDOUT bit is the expected calculated DED parity and DEDIN is the actual value from a Flash read operation. When no error is present, DEDIN equals DEDOUT.

Both single and double-bit errors can be generated in both the read and write data paths. Read path Fault injection first reads the Flash data and then modifies it prior to entering the ECC logic. Write path Fault injection modifies the actual data prior to it being written into the target Flash and will cause an EEC error on subsequent Flash read. The following procedure is used to inject a Fault: 1. 2. 3. 4. 5. 6. Load Flash target address into the ECCADDR register. Select 1st Fault bit determined by FLT1PTRx (ECCCONH<7:0>). The target bit is inverted to create the Fault. If a double Fault is desired, select the 2nd Fault bit determined by FLT2PTRx (ECCCONH<15:8>), otherwise set to all `1's. Write the NVMKEY unlock sequence. Enable the ECC Fault injection logic by setting the FLTINJ bit (ECCCONL<0>) Perform a read or write to the Flash target address. 2017-2018 Microchip Technology Inc. 3.3.4 CONTROL REGISTERS Five SFRs are used to write and erase the Program Flash Memory: NVMCON, NVMKEY, NVMADR, NVMADRU and NVMSRCADRL/H. The NVMCON register (Register 3-4) selects the operation to be performed (page erase, word/row program, Inactive Partition erase) and initiates the program or erase cycle. NVMKEY (Register 3-7) is a write-only register that is used for write protection. To start a programming or erase sequence, the user application must consecutively write 0x55 and 0xAA to the NVMKEY register. There are two NVM Address registers: NVMADR and NVMADRU. These two registers, when concatenated, form the 24-bit Effective Address (EA) of the selected word/row for programming operations, or the selected page for erase operations. The NVMADRU register is used to hold the upper 8 bits of the EA, while the NVMADR register is used to hold the lower 16 bits of the EA. For row programming operation, data to be written to Program Flash Memory is written into data memory space (RAM) at an address defined by the NVMSRCADRL/H register (location of first element in row programming data).

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Reset" (DS70602) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The Reset module combines all Reset sources and controls the device Master Reset Signal, SYSRST. The following is a list of device Reset sources: * * * * * * * * POR: Power-on Reset BOR: Brown-out Reset MCLR: Master Clear Pin Reset SWR: RESET Instruction WDTO: Watchdog Timer Time-out Reset CM: Configuration Mismatch Reset TRAPR: Trap Conflict Reset IOPUWR: Illegal Condition Device Reset - Illegal Opcode Reset - Uninitialized W Register Reset - Security Reset Note: Refer to the specific peripheral section or Section 3.2 "Master Memory Organization" of this data sheet for register Reset states. All types of device Reset set a corresponding status bit in the RCON register to indicate the type of Reset (see Register 3-15). A POR clears all the bits, except for the BOR and POR bits (RCON<1:0>) that are set. The user application can set or clear any bit, at any time, during code execution. The RCON bits only serve as status bits. Setting a particular Reset status bit in software does not cause a device Reset to occur. The RCON register also has other bits associated with the Watchdog Timer and device power-saving states. The function of these bits is discussed in other sections of this data sheet. Note: A simplified block diagram of the Reset module is shown in Figure 3-16. FIGURE 3-16: Any active source of Reset will make the SYSRST signal active. On system Reset, some of the registers associated with the CPU and peripherals are forced to a known Reset state, and some are unaffected. The status bits in the RCON register should be cleared after they are read so that the next RCON register value after a device Reset is meaningful. For all Resets, the default clock source is determined by the FNOSC<2:0> bits in the FOSCSEL Configuration register. The value of the FNOSCx bits is loaded into the NOSC<2:0> (OSCCON<10:8>) bits on Reset, which in turn, initializes the system clock.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Interrupts" (DS70000600) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The dsPIC33CH128MP508 family interrupt controller reduces the numerous peripheral interrupt request signals to a single interrupt request signal to the dsPIC33CH128MP508 family CPU. 3.5.1.1 The Alternate Interrupt Vector Table (AIVT), shown in Figure 3-18, is available only when the Boot Segment (BS) is defined and the AIVT has been enabled. To enable the Alternate Interrupt Vector Table, the Configuration bit, AIVTDIS in the FSEC register, must be programmed and the AIVTEN bit must be set (INTCON2<8> = 1). When the AIVT is enabled, all interrupt and exception processes use the alternate vectors instead of the default vectors. The AIVT begins at the start of the last page of the Boot Segment, defined by BSLIM<12:0>. The second half of the page is no longer usable space. The Boot Segment must be at least two pages to enable the AIVT. Note: The interrupt controller has the following features: * Six Processor Exceptions and Software Traps * Seven User-Selectable Priority Levels * Interrupt Vector Table (IVT) with a Unique Vector for each Interrupt or Exception Source * Fixed Priority within a Specified User Priority Level * Fixed Interrupt Entry and Return Latencies * Alternate Interrupt Vector Table (AIVT) for Debug Support 3.5.1 INTERRUPT VECTOR TABLE The dsPIC33CH128MP508 family Interrupt Vector Table (IVT), shown in Figure 3-17, resides in program memory, starting at location, 000004h. The IVT contains six non-maskable trap vectors and up to 246 sources of interrupts. In general, each interrupt source has its own vector. Each interrupt vector contains a 24-bit wide address. The value programmed into each interrupt vector location is the starting address of the associated Interrupt Service Routine (ISR). Interrupt vectors are prioritized in terms of their natural priority. This priority is linked to their position in the vector table. Lower addresses generally have a higher natural priority. For example, the interrupt associated with Vector 0 takes priority over interrupts at any other vector address. 2017-2018 Microchip Technology Inc. Alternate Interrupt Vector Table Although the Boot Segment must be enabled in order to enable the AIVT, application code does not need to be present inside of the Boot Segment. The AIVT (and IVT) will inherit the Boot Segment code protection. The AIVT supports debugging by providing a means to switch between an application and a support environment without requiring the interrupt vectors to be reprogrammed. This feature also enables switching between applications for evaluation of different software algorithms at run time. 3.5.2 RESET SEQUENCE A device Reset is not a true exception because the interrupt controller is not involved in the Reset process. The dsPIC33CH128MP508 family devices clear their registers in response to a Reset, which forces the PC to zero. The device then begins program execution at location, 0x000000. A GOTO instruction at the Reset address can redirect program execution to the appropriate start-up routine. Note: Any unimplemented or unused vector locations in the IVT should be programmed with the address of a default interrupt handler routine that contains a RESET instruction.

This product page contains the latest updates and additional information. 3.5.3.1 Key Resources * "Interrupts" (DS70000600) in the "dsPIC33/ PIC24 Family Reference Manual" * Code Samples * Application Notes * Software Libraries * Webinars * All Related "dsPIC33/PIC24 Family Reference Manual" Sections * Development Tools 3.5.4 INTERRUPT CONTROL AND STATUS REGISTERS The dsPIC33CH128MP508 family devices implement the following registers for the interrupt controller: * * * * * INTCON1 INTCON2 INTCON3 INTCON4 INTTREG 3.5.4.1 INTCON1 through INTCON4 Global interrupt control functions are controlled from INTCON1, INTCON2, INTCON3 and INTCON4. INTCON1 contains the Interrupt Nesting Disable bit (NSTDIS), as well as the control and status flags for the processor trap sources. The INTCON2 register controls external interrupt request signal behavior, contains the Global Interrupt Enable bit (GIE) and the Alternate Interrupt Vector Table Enable bit (AIVTEN). INTCON3 contains the status flags for the Auxiliary PLL and DO stack overflow status trap sources. The INTCON4 register contains the Generated Hard Trap Status bit (SGHT). 3.5.4.2 Software IFSx The IFSx registers maintain all of the interrupt request flags. Each source of interrupt has a status bit, which is set by the respective peripherals or external signal and is cleared via software. 2017-2018 Microchip Technology Inc. IECx The IECx registers maintain all of the interrupt enable bits. These control bits are used to individually enable interrupts from the peripherals or external signals. 3.5.4.4 IPCx The IPCx registers are used to set the Interrupt Priority Level (IPL) for each source of interrupt. Each user interrupt source can be assigned to one of seven priority levels. 3.5.4.5 INTTREG The INTTREG register contains the associated interrupt vector number and the new CPU Interrupt Priority Level, which are latched into the Vector Number (VECNUM<7:0>) and Interrupt Level bits (ILR<3:0>) fields in the INTTREG register. The new Interrupt Priority Level is the priority of the pending interrupt. The interrupt sources are assigned to the IFSx, IECx and IPCx registers in the same sequence as they are listed in Table 3-23. For example, INT0 (External Interrupt 0) is shown as having Vector Number 8 and a natural order priority of 0. Thus, the INT0IF bit is found in IFS0<0>, the INT0IE bit in IEC0<0> and the INT0IP<2:0> bits in the first position of IPC0 (IPC0<2:0>). 3.5.4.6 Status/Control Registers Although these registers are not specifically part of the interrupt control hardware, two of the CPU Control registers contain bits that control interrupt functionality. For more information on these registers, refer to "dsPIC33E Enhanced CPU" (DS70005158) in the "dsPIC33/PIC24 Family Reference Manual". * The CPU STATUS Register, SR, contains the IPL<2:0> bits (SR<7:5>). These bits indicate the current CPU Interrupt Priority Level. The user software can change the current CPU Interrupt Priority Level by writing to the IPLx bits. * The CORCON register contains the IPL3 bit, which together with IPL<2:0>, also indicates the current CPU priority level. IPL3 is a read-only bit so that trap events cannot be masked by the user software. All Interrupt registers are described in Register 3-18 through Register 3-22 in the following pages.

DS70005319B-page 111 dsPIC33CH128MP508 FAMILY 3.6 Master I/O Ports Note: Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "I/O Ports with Edge Detect" (DS70005322) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: The I/O ports are shared by Master core and Slave core. All input goes to both the Master and Slave. The I/O ownership is defined by the Configuration bits. 3: The TMS pin function may be active multiple times during ICSPTM device erase, programming and debugging. When the TMS function is active, the integrated pull-up resistor will pull the pin to VDD. Proper care should be taken if there are sensitive circuits connected on the TMS pin during programming/erase and debugging. Many of the device pins are shared among the peripherals and the Parallel I/O ports. All I/O input ports feature Schmitt Trigger inputs for improved noise immunity. The Master and Slave have the same number of I/O ports and are shared. The Master PORT registers are located in the Master SFR and the Slave PORT registers are located in the Slave SFR, respectively. Some of the key features of the I/O ports are: The output functionality of the ports is defined by the Configuration registers, FCFGPRA0 to FCFGPRE0. When these Configuration bits are maintained as `1', the Master owns the pin (only the output function); when the bits are `0', the ownership of that specific pin belongs to the Slave. The input function of the I/O is valid for both Master and Slave. The Configuration registers, FCFGPRA0 to FCFGPRE0, do not have any control over the input function. 3.6.1 PARALLEL I/O (PIO) PORTS All port pins have 12 registers directly associated with their operation as digital I/Os. The Data Direction register (TRISx) determines whether the pin is an input or an output. If the data direction bit is a `1', then the pin is an input. All port pins are defined as inputs after a Reset. Reads from the latch (LATx), read the latch. Writes to the latch, write the latch. Reads from the port (PORTx), read the port pins, while writes to the port pins, write the latch. Any bit and its associated data and control registers that are not valid for a particular device are disabled. This means the corresponding LATx and TRISx registers, and the port pin are read as zeros. When a pin is shared with another peripheral or function that is defined as an input only, it is nevertheless regarded as a dedicated port because there is no other competing source of outputs.

This is controlled by the Open-Drain Enable for PORTx register, ODCx, associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain output. The open-drain feature allows the generation of outputs, other than VDD, by using external pull-up resistors. The maximum open-drain voltage allowed on any pin is the same as the maximum VIH specification for that particular pin. 3.6.2 CONFIGURING ANALOG AND DIGITAL PORT PINS The ANSELx registers control the operation of the analog port pins. The port pins that are to function as analog inputs or outputs must have their corresponding ANSELx and TRISx bits set. In order to use port pins for I/O functionality with digital modules, such as timers, UARTs, etc., the corresponding ANSELx bit must be cleared. The ANSELx registers have a default value of 0xFFFF; therefore, all pins that share analog functions are analog (not digital) by default. Pins with analog functions affected by the ANSELx registers are listed with a buffer type of analog in the Pinout I/O Descriptions (see Table 1-1). When the PORTx register is read, all pins configured as analog input channels are read as cleared (a low level). Pins configured as digital inputs do not convert an analog input. Analog levels on any pin, defined as a digital input (including the ANx pins), can cause the input buffer to consume current that exceeds the device specifications. 3.6.2.1 I/O Port Write/Read Timing One instruction cycle is required between a port direction change or port write operation and a read operation of the same port. Typically, this instruction would be a NOP. The following registers are in the PORT module: * * * * * * * * * * * * Register 3-23: ANSELx (one per port) Register 3-24: TRISx (one per port) Register 3-25: PORTx (one per port) Register 3-26: LATx (one per port) Register 3-27: ODCx (one per port) Register 3-28: CNPUx (one per port) Register 3-29: CNPDx (one per port) Register 3-30: CNCONx (one per port - optional) Register 3-31: CNEN0x (one per port) Register 3-32: CNSTATx (one per port - optional) Register 3-33: CNEN1x (one per port) Register 3-34: CNFx (one per port) If the TRISx bit is cleared (output) while the ANSELx bit is set, the digital output level (VOH or VOL) is converted by an analog peripheral, such as the ADC module or comparator module. 2017-2018 Microchip Technology Inc.

This feature can detect input Change-of-States, even in Sleep mode, when the clocks are disabled. Every I/O port pin can be selected (enabled) for generating an interrupt request on a Change-of-State. Five control registers are associated with the Change Notification (CN) functionality of each I/O port. To enable the Change Notification feature for the port, the ON bit (CNCONx<15>) must be set. The CNEN0x and CNEN1x registers contain the CN interrupt enable control bits for each of the input pins. The setting of these bits enables a CN interrupt for the corresponding pins. Also, these bits, in combination with the CNSTYLE bit (CNCONx<11>), define a type of transition when the interrupt is generated. Possible CN event options are listed in Table 3-29. TABLE 3-29: CHANGE NOTIFICATION EVENT OPTIONS CNSTYLE Bit CNEN1x CNEN0x (CNCONx<11>) Bit Bit Change Notification Event Description 3.6.5 PERIPHERAL PIN SELECT (PPS) A major challenge in general purpose devices is providing the largest possible set of peripheral features, while minimizing the conflict of features on I/O pins. The challenge is even greater on low pin count devices. In an application where more than one peripheral needs to be assigned to a single pin, inconvenient work arounds in application code, or a complete redesign, may be the only option. Peripheral Pin Select configuration provides an alternative to these choices by enabling peripheral set selection and placement on a wide range of I/O pins. By increasing the pinout options available on a particular device, users can better tailor the device to their entire application, rather than trimming the application to fit the device. The Peripheral Pin Select configuration feature operates over a fixed subset of digital I/O pins. Users may independently map the input and/or output of most digital peripherals to any one of these I/O pins. Hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping once it has been established. 3.6.6 AVAILABLE PINS 0 Does not matter 0 Disabled 0 Does not matter 1 Detects a mismatch between the last read state and the current state of the pin 1 0 0 Disabled The number of available pins is dependent on the particular device and its pin count. Pins that support the Peripheral Pin Select feature include the label, "RPn", in their full pin designation, where "n" is the remappable pin number. "RP" is used to designate pins that support both remappable input and output functions. 1 0 1 Detects a positive transition only (from `0' to `1') 3.6.7 1 1 0 Detects a negative transition only (from `1' to `0') 1 1 1 Detects both positive and negative transitions The peripherals managed by the Peripheral Pin Select are all digital only peripherals. These include general serial communications (UART and SPI), general purpose timer clock inputs, timer-related peripherals (input capture and output compare) and interrupt-on-change inputs. The CNSTATx register indicates whether a change occurred on the corresponding pin since the last read of the PORTx bit. In addition to the CNSTATx register, the CNFx register is implemented for each port. This register contains flags for Change Notification events. These flags are set if the valid transition edge, selected in the CNEN0x and CNEN1x registers, is detected. CNFx stores the occurrence of the event. CNFx bits must be cleared in software to get the next Change Notification interrupt. The CN interrupt is generated only for the I/Os configured as inputs (corresponding TRISx bits must be set). Note: Pull-ups and pull-downs on Input Change Notification pins should always be disabled when the port pin is configured as a digital output. 2017-2018 Microchip Technology Inc. AVAILABLE PERIPHERALS In comparison, some digital only peripheral modules are never included in the Peripheral Pin Select feature. This is because the peripheral's function requires special I/O circuitry on a specific port and cannot be easily connected to multiple pins. One example includes I2C modules. A similar requirement excludes all modules with analog inputs, such as the A/D Converter (ADC) A key difference between remappable and nonremappable peripherals is that remappable peripherals are not associated with a default I/O pin. The peripheral must always be assigned to a specific I/O pin before it can be used. In contrast, non-remappable peripherals are always available on a default pin, assuming that the peripheral is active and not conflicting with another peripheral. DS70005319B-page 123 dsPIC33CH128MP508 FAMILY When a remappable peripheral is active on a given I/O pin, it takes priority over all other digital I/Os and digital communication peripherals associated with the pin. Priority is given regardless of the type of peripheral that is mapped. Remappable peripherals never take priority over any analog functions associated with the pin. 3.6.8 CONTROLLING CONFIGURATION CHANGES Because peripheral mapping can be changed during run time, some restrictions on peripheral remapping are needed to prevent accidental configuration changes. The dsPIC33CH128MP508 devices have implemented the control register lock sequence. 3.6.8.1 CONTROL REGISTER LOCK Under normal operation, writes to the RPINRx and RPORx registers are not allowed. Attempted writes will appear to execute normally, but the contents of the registers will remain unchanged. To change these registers, they must be unlocked in hardware. The register lock is controlled by the IOLOCK bit (RPCON<11>). Setting IOLOCK prevents writes to the control registers; clearing IOLOCK allows writes. To set or clear IOLOCK, the NVMKEY unlock sequence must be executed: 1. 2. 3. Write 0x55 to NVMKEY. Write 0xAA to NVMKEY. Clear (or set) IOLOCK as a single operation. IOLOCK remains in one state until changed. This allows all of the Peripheral Pin Selects to be configured with a single unlock sequence, followed by an update to all of the control registers. Then, IOLOCK can be set with a second lock sequence. Note: MPLAB(R) C30 provides a built-in C language function for unlocking and modifying the RPCON register: __builtin_write_RPCON(value); For more information, see the MPLAB C30 Help files. 3.6.9 CONSIDERATIONS FOR PERIPHERAL PIN SELECTION The ability to control Peripheral Pin Selection introduces several considerations into application design that most users would never think of otherwise. This is particularly true for several common peripherals, which are only available as remappable peripherals. The main consideration is that the Peripheral Pin Selects are not available on default pins in the device's default (Reset) state. More specifically, because all RPINRx registers reset to `1's and RPORx registers reset to `0's, this means all PPS inputs are tied to VSS, while all PPS outputs are disconnected. This means that before any other application code is executed, the user must initialize the device with the proper peripheral configuration. Because the IOLOCK bit resets in the unlocked state, it is not necessary to execute the unlock sequence after the device has come out of Reset. For application safety, however, it is always better to set IOLOCK and lock the configuration after writing to the control registers. The NVMKEY unlock sequence must be executed as an Assembly language routine. If the bulk of the application is written in C, or another high-level language, the unlock sequence should be performed by writing in-line assembly or by using the __builtin_write_RPCON(value) function provided by the compiler. Choosing the configuration requires a review of all Peripheral Pin Selects and their pin assignments, particularly those that will not be used in the application. In all cases, unused pin-selectable peripherals should be disabled completely. Unused peripherals should have their inputs assigned to an unused RPn pin function. I/O pins with unused RPn functions should be configured with the null peripheral output. 3.6.10 INPUT MAPPING The inputs of the Peripheral Pin Select options are mapped on the basis of the peripheral. That is, a control register associated with a peripheral dictates the pin it will be mapped to. The RPINRx registers are used to configure peripheral input mapping. Each register contains sets of 8-bit fields, with each set associated with one of the remappable peripherals. Programming a given peripheral's bit field with an appropriate 8-bit index value maps the RPn pin with the corresponding value, or internal signal, to that peripheral. See Table 3-30 for a list of available inputs. For example, Figure 3-20 illustrates remappable pin selection for the U1RX input.

DS70005319B-page 127 dsPIC33CH128MP508 FAMILY 3.6.11 VIRTUAL CONNECTIONS The dsPIC33CH128MP508 devices support six Master virtual RPn pins (RP176-RP181), which are identical in functionality to all other RPn pins, with the exception of pinouts. These six pins are internal to the devices and are not connected to a physical device pin. These pins provide a simple way for inter-peripheral connection without utilizing a physical pin. For example, the output of the analog comparator can be connected to RP176 and the PWM Fault input can be configured for RP176 as well. This configuration allows the analog comparator to trigger PWM Faults without the use of an actual physical pin on the device. 3.6.12 SLAVE PPS INPUTS TO MASTER CORE PPS The dsPIC33CH128MP508 Slave core subsystem PPS has connections to the Master core subsystem virtual PPS (RPV5-RPV0) output blocks. These inputs are mapped as S1RP175, S1RP174, S1RP173, S1RP172, S1RP171 and S1RP170. The RPn inputs, RP1-RP13, are connected to internal signals from both the Master and Slave core subsystems. Additionally, the Master core virtual output PPS blocks (RPV5-RPV0) are connected to the Slave core PPS circuitry. DS70005319B-page 128 There are virtual pins in PPS to share between Master and Slave: * * * * * * * * * * * * RP181 is for Master input (RPV5) RP180 is for Master input (RPV4) RP179 is for Master input (RPV3) RP178 is for Master input (RPV2) RP177 is for Master input (RPV1) RP176 is for Master input (RPV0) RP175 is for Slave input (S1RPV5) RP174 is for Slave input (S1RPV4) RP173 is for Slave input (S1RPV3) RP172 is for Slave input (S1RPV2) RP171 is for Slave input (S1RPV1) RP170 is for Slave input (S1RPV0) The idea of the RPVn (Remappable Pin Virtual) is to interconnect between the Master and Slave without an I/O pin. For example, the Master UART receiver can be connected to the Slave UART transmit using RPVn and data communication can happen from Slave to Master without using any physical pin. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY TABLE 3-31: SELECTABLE INPUT SOURCES (MAPS INPUT TO FUNCTION) Input Name(1) Function Name Register Register Bits External Interrupt 1 INT1 RPINR0 INT1R<7:0> External Interrupt 2 INT2 RPINR1 INT2R<7:0> External Interrupt 3 INT3 RPINR1 INT3R<7:0> Timer1 External Clock T1CK RPINR2 T1CK<7:0> SCCP Timer1 TCKI1 RPINR3 TCKI1R<7:0> SCCP Capture 1 ICM1 RPINR3 ICM1R<7:0> SCCP Timer2 TCKI2 RPINR4 TCKI2R<7:0> SCCP Capture 2 ICM2 RPINR4 ICM2R<7:0> SCCP Timer3 TCKI3 RPINR5 TCKI3R<7:0> SCCP Capture 3 ICM3 RPINR5 ICM3R<7:0> SCCP Timer4 TCKI4 RPINR6 TCKI4R<7:0> SCCP Capture 4 ICM4 RPINR6 ICM4R<7:0> SCCP Timer5 TCKI5 RPINR7 TCKI5R<7:0> SCCP Capture 5 ICM5 RPINR7 ICM5R<7:0> SCCP Timer6 TCKI6 RPINR8 TCKI6R<7:0> SCCP Capture 6 ICM6 RPINR8 ICM6R<7:0> SCCP Timer7 TCKI7 RPINR9 TCKI7R<7:0> SCCP Capture 7 ICM7 RPINR9 ICM7R<7:0> SCCP Timer8 TCKI8 RPINR10 TCKI8R<7:0> SCCP Capture 8 ICM8 RPINR10 ICM8R<7:0> SCCP Fault A OCFA RPINR11 OCFAR<7:0> SCCP Fault B OCFB RPINR11 OCFBR<7:0> PWM Input 8 PCI8 RPINR12 PCI8R<7:0> PWM Input 9 PCI9 RPINR12 PCI9R<7:0> PWM Input 10 PCI10 RPINR13 PCI10R<7:0> PWM Input 11 PCI11 RPINR13 PCI11R<7:0> QEI Input A QEIA1 RPINR14 QEIA1R<7:0> QEI Input B QEIB1 RPINR14 QEIB1R<7:0> QEI Index 1 Input QEINDX1 RPINR15 QEINDX1R<7:0> QEI Home 1 Input QEIHOM1 RPINR15 QEIHOM1R<7:0> UART1 Receive UART1 Data-Set-Ready UART2 Receive U1RX RPINR18 U1RXR<7:0> U1DSR RPINR18 U1DSRR<7:0> U2RX RPINR19 U2RXR<7:0> U2DSRR<7:0> U2DSR RPINR19 SPI1 Data Input SDI1 RPINR20 SDI1R<7:0> SPI1 Clock Input SCK1IN RPINR20 SCK1R<7:0> SPI1 Slave Select SS1 RPINR21 SS1R<7:0> UART2 Data-Set-Ready Reference Clock Input REFOI RPINR21 REFOIR<7:0> SPI2 Data Input SDI2 RPINR22 SDI2R<7:0> SPI2 Clock Input SCK2IN RPINR22 SCK2R<7:0> SS2 RPINR23 SS2R<7:0> U1CTS RPINR23 U1CTSR<7:0> SPI2 Slave Select UART1 Clear-to-Send Note 1: Unless otherwise noted, all inputs use the Schmitt Trigger input buffers. 2017-2018 Microchip Technology Inc.

In this case, a control register associated with a particular pin dictates the peripheral output to be mapped. The RPORx registers are used to control output mapping. Each register contains sets of 6-bit fields, with each set associated with one RPn pin (see Register 3-68 through Register 3-90). The value of the bit field corresponds to one of the peripherals and that peripheral's output is mapped to the pin (see Table 3-33 and Figure 3-21). MAPPING LIMITATIONS The control schema of the peripheral select pins is not limited to a small range of fixed peripheral configurations. There are no mutual or hardware-enforced lockouts between any of the peripheral mapping SFRs. Literally, any combination of peripheral mappings, across any or all of the RPn pins, is possible. This includes both many-to-one and one-to-many mappings of peripheral inputs, and outputs to pins. While such mappings may be technically possible from a configuration point of view, they may not be supportable from an electrical point of view (see Table 3-32). A null output is associated with the output register Reset value of `0'. This is done to ensure that remappable outputs remain disconnected from all output pins by default.

I/O HELPFUL TIPS In some cases, certain pins, as defined in Table 24-18 under "Injection Current", have internal protection diodes to VDD and VSS. The term, "Injection Current", is also referred to as "Clamp Current". On designated pins, with sufficient external current-limiting precautions by the user, I/O pin input voltages are allowed to be greater or lesser than the data sheet absolute maximum ratings, with respect to the VSS and VDD supplies. Note that when the user application forward biases either of the high or low-side internal input clamp diodes, that the resulting current being injected into the device that is clamped internally by the VDD and VSS power rails, may affect the ADC accuracy by four to six counts. I/O pins that are shared with any analog input pin (i.e., ANx) are always analog pins, by default, after any Reset. Consequently, configuring a pin as an analog input pin automatically disables the digital input pin buffer and any attempt to read the digital input level by reading PORTx or LATx will always return a `0', regardless of the digital logic level on the pin. To use a pin as a digital I/O pin on a shared ANx pin, the user application needs to configure the Analog Select for PORTx registers in the I/O ports module (i.e., ANSELx) by setting the appropriate bit that corresponds to that I/O port pin to a `0'. Note: Although it is not possible to use a digital input pin when its analog function is enabled, it is possible to use the digital I/O output function, TRISx = 0x0, while the analog function is also enabled. However, this is not recommended, particularly if the analog input is connected to an external analog voltage source, which would create signal contention between the analog signal and the output pin driver. DS70005319B-page 134 3. 4. 5. Most I/O pins have multiple functions. Referring to the device pin diagrams in this data sheet, the priorities of the functions allocated to any pins are indicated by reading the pin name, from left-to-right. The left most function name takes precedence over any function to its right in the naming convention. For example: AN14/ISRC1/RP50/RC2; this indicates that AN14 is the highest priority in this example and will supersede all other functions to its right in the list. Those other functions to its right, even if enabled, would not work as long as any other function to its left was enabled. This rule applies to all of the functions listed for a given pin. Each pin has an internal weak pull-up resistor and pull-down resistor that can be configured using the CNPUx and CNPDx registers, respectively. These resistors eliminate the need for external resistors in certain applications. The internal pull-up is up to ~(VDD - 0.8), not VDD. This value is still above the minimum VIH of CMOS and TTL devices. When driving LEDs directly, the I/O pin can source or sink more current than what is specified in the VOH/IOH and VOL/IOL DC characteristics specification. The respective IOH and IOL current rating only applies to maintaining the corresponding output at or above the VOH, and at or below the VOL levels. However, for LEDs, unlike digital inputs of an externally connected device, they are not governed by the same minimum VIH/VIL levels. An I/O pin output can safely sink or source any current less than that listed in the Absolute Maximum Ratings in Section 24.0 "Electrical Characteristics" of this data sheet. For example: VOH = 2.4v @ IOH = -8 mA and VDD = 3.3V The maximum output current sourced by any 8 mA I/O pin = 12 mA. LED source current < 12 mA is technically permitted. Refer to the VOH/IOH graphs in Section 25.0 "DC and AC Device Characteristics Graphs" for additional information. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 6. The Peripheral Pin Select (PPS) pin mapping rules are as follows: a) Only one "output" function can be active on a given pin at any time, regardless if it is a dedicated or remappable function (one pin, one output). b) It is possible to assign a "remappable output" function to multiple pins and externally short or tie them together for increased current drive. c) If any "dedicated output" function is enabled on a pin, it will take precedence over any remappable "output" function. d) If any "dedicated digital" (input or output) function is enabled on a pin, any number of "input" remappable functions can be mapped to the same pin. e) If any "dedicated analog" function(s) are enabled on a given pin, "digital input(s)" of any kind will all be disabled, although a single "digital output", at the user's cautionary discretion, can be enabled and active as long as there is no signal contention with an external analog input signal. For example, it is possible for the ADC to convert the digital output logic level, or to toggle a digital output on a comparator or ADC input, provided there is no external analog input, such as for a built-in self-test. f) Any number of "input" remappable functions can be mapped to the same pin(s) at the same time, including to any pin with a single output from either a dedicated or remappable "output". g) The TRISx registers control only the digital I/O output buffer. Any other dedicated or remappable active "output" will automatically override the TRISx setting. The TRISx register does not control the digital logic "input" buffer. Remappable digital "inputs" do not automatically override TRISx settings, which means that the TRISx bit must be set to input for pins with only remappable input function(s) assigned. h) All analog pins are enabled by default after any Reset and the corresponding digital input buffer on the pin has been disabled. Only the Analog Select for PORTx (ANSELx) registers control the digital input buffer, not the TRISx register. The user must disable the analog function on a pin using the Analog Select for PORTx registers in order to use any "digital input(s)" on a corresponding pin, no exceptions. 2017-2018 Microchip Technology Inc. 3.6.16 I/O PORTS RESOURCES Many useful resources are provided on the main product page of the Microchip web site for the devices listed in this data sheet.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Deadman Timer (DMT)" (DS70005155) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). DMT can be enabled in the Configuration fuse or by software in the DMTCON register by setting the ON bit. The DMT consists of a 32-bit counter with a time-out count match value, as specified by the two 16-bit Configuration Fuse registers: FDMTCNTL and FDMTCNTH. A DMT is typically used in mission-critical and safetycritical applications, where any single failure of the software functionality and sequencing must be detected. Table 3-41 shows an overview of the DMT module. TABLE 3-41: 2: The Slave core does not have any DMT module; only the Master has the DMT. The primary function of the Deadman Timer (DMT) is to interrupt the processor in the event of a software malfunction. The DMT, which works on the system clock, is a free-running instruction fetch timer, which is clocked whenever an instruction fetch occurs, until a count match occurs. Instructions are not fetched when the processor is in Sleep mode.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "CAN Flexible Data-Rate (FD) Protocol Module" (DS70005340 in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Only the Master core has a CAN FD module. Table 3-42 shows an overview of the CAN FD module. TABLE 3-42: CAN FD MODULE OVERVIEW Number of CAN Modules Identical (Modules) Master Core 1 NA Slave Core None NA 3.8.1 FEATURES The CAN FD module has the following features: General * Nominal (Arbitration) Bit Rate up to 1 Mbps * Data Bit Rate up to 8 Mbps * CAN FD Controller modes: - Mixed CAN 2.0B and CAN FD mode - CAN 2.0B mode * Conforms to ISO11898-1:2015 Message FIFOs * Seven FIFOs, Configurable as Transmit or Receive FIFOs * One Transmit Queue (TXQ) * Transmit Event FIFO (TEF) with 32-Bit Timestamp Message Transmission * Message Transmission Prioritization: - Based on priority bit field, and/or - Message with lowest ID gets transmitted first using the TXQ * Programmable Automatic Retransmission Attempts: Unlimited, Three Attempts or Disabled DS70005319B-page 178 Message Reception * 16 Flexible Filter and Mask Objects. * Each Object can be Configured to Filter either: - Standard ID + first 18 data bits or - Extended ID * 32-Bit Timestamp. * The CAN FD Bit Stream Processor (BSP) Implements the Medium Access Control of the CAN FD Protocol Described in ISO11898-1:2015. It serializes and deserializes the bit stream, encodes and decodes the CAN FD frames, manages the medium access, Acknowledges frames, and detects and signals errors. * The TX Handler Prioritizes the Messages that are Requested for Transmission by the Transmit FIFOs. It uses the RAM interface to fetch the transmit data from RAM and provides it to the BSP for transmission. * The BSP provides Received Messages to the RX Handler. The RX handler uses acceptance filters to filter out messages that shall be stored in the Receive FIFOs. It uses the RAM interface to store received data into RAM. * Each FIFO can be Configured either as a Transmit or Receive FIFO. The FIFO control keeps track of the FIFO head and tail, and calculates the user address. In a TX FIFO, the user address points to the address in RAM where the data for the next transmit message shall be stored. In an RX FIFO, the user address points to the address in RAM where the data of the next receive message shall be read. The user notifies the FIFO that a message was written to or read from RAM by incrementing the head/tail of the FIFO. * The Transmit Queue (TXQ) is a Special Transmit FIFO that Transmits the Messages based on the ID of the Messages Stored in the Queue. * The Transmit Event FIFO (TEF) Stores the Message IDs of the Transmitted Messages. * A Free-Running Time Base Counter is used to Timestamp Received Messages. Messages in the TEF can also be timestamped. * The CAN FD Controller module Generates Interrupts when New Messages are Received or when Messages were Transmitted Successfully. Figure 3-23 shows the CAN FD system block diagram. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY FIGURE 3-23: CAN FD MODULE BLOCK DIAGRAM C1TX TX Handler Timestamping TX Prioritization Interrupt Control C1RX RX Handler Error Handling Diagnostics Filter and Masks Device RAM TEF TXQ FIFO 1 FIFO 7 Message Object 0 Message Object 0 Message Object 0 Message Object 0 * * * * * * * * * * Message Object 31 Message Object 31 Message Object 31 Message Object 31 2017-2018 Microchip Technology Inc. * * * * * DS70005319B-page 179 dsPIC33CH128MP508 FAMILY 3.8.2 CAN CONTROL/STATUS REGISTERS REGISTER 3-102: C1CONH: CAN CONTROL REGISTER HIGH R/W-0 R/W-0 R/W-0 R/W-0 S/HC-0 R/W-1 R/W-0 R/W-0 TXBWS3 TXBWS2 TXBWS1 TXBWS0 ABAT REQOP2 REQOP1 REQOP0 bit 15 bit 8 R-1 R-0 R-0 R/W-1 R/W-1 R/W-0 R/W-0 R/W-0 OPMOD2 OPMOD1 OPMOD0 TXQEN(1) STEF(1) SERRLOM(1) ESIGM(1) RTXAT(1) bit 7 bit 0 Legend: S = Settable bit HC = Hardware Clearable bit R = Readable bit W = Writable bit U = Unimplemented bit, read as `0' -n = Value at POR `1' = Bit is set `0' = Bit is cleared x = Bit is unknown bit 15-12 TXBWS<3:0>: Transmit Bandwidth Sharing bits 1111-1100 = 4096 1011 = 2048 1010 = 1024 1001 = 512 1000 = 256 0111 = 128 0110 = 64 0101 = 32 0100 = 16 0011 = 8 0010 = 4 0001 = 2 0000 = No delay bit 11 ABAT: Abort All Pending Transmissions bit 1 = Signals all transmit buffers to abort transmission 0 = Module will clear this bit when all transmissions are aborted bit 10-8 REQOP<2:0>: Request Operation Mode bits 111 = Sets Restricted Operation mode 110 = Sets Normal CAN 2.0 mode; error frames on CAN FD frames 101 = Sets External Loopback mode 100 = Sets Configuration mode 011 = Sets Listen Only mode 010 = Sets Internal Loopback mode 001 = Sets Disable mode 000 = Sets Normal CAN FD mode; supports mixing of full CAN FD and classic CAN 2.0 frames bit 7-5 OPMOD<2:0>: Operation Mode Status bits 111 = Module is in Restricted Operation mode 110 = Module is in Normal CAN 2.0 mode; error frames on CAN FD frames 101 = Module is in External Loopback mode 100 = Module is in Configuration mode 011 = Module is in Listen Only mode 010 = Module is in Internal Loopback mode 001 = Module is in Disable mode 000 = Module is in Normal CAN FD mode; supports mixing of full CAN FD and classic CAN 2.0 frames Note 1: These bits can only be modified in Configuration mode (OPMOD<2:0> = 100).

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "12-Bit High-Speed, Multiple SARs A/D Converter (ADC)" (DS70005213) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: This section describes the Master ADC module, which implements one shared core, and no dedicated cores. dsPIC33CH128MP508 devices have a high-speed, 12-bit Analog-to-Digital Converter (ADC) that features a low conversion latency, high resolution and oversampling capabilities to improve performance in AC/ DC and DC/DC power converters. The Master implements one SAR core ADC. 3.9.1 MASTER ADC FEATURES OVERVIEW The high-speed, 12-bit multiple SARs Analog-to-Digital Converter (ADC) includes the following features: * One Shared (common) Core * User-Configurable Resolution of up to 12 Bits * Up to 3.5 Msps Conversion Rate per Channel at 12-Bit Resolution * Low Latency Conversion * Up to 20 Analog Input Channels, with a Separate 16-Bit Conversion Result Register for each Input Channel * Conversion Result can be Formatted as Unsigned or Signed Data, on a per Channel Basis, for All Channels 2017-2018 Microchip Technology Inc. * Channel Scan Capability * Multiple Conversion Trigger Options, including: - PWM triggers from Master and Slave CPU cores - SCCP modules triggers - CLC modules triggers - External pin trigger event (ADTRG31) - Software trigger * Four Integrated Digital Comparators with Dedicated Interrupts: - Multiple comparison options - Assignable to specific analog inputs * Four Oversampling Filters with Dedicated Interrupts: - Provide increased resolution - Assignable to a specific analog input Simplified block diagrams of the 12-bit ADC are shown in Figure 3-24 and Figure 3-25. The analog inputs (channels) are connected through multiplexers and switches to the Sample-and-Hold (S&H) circuit of the ADC core. The core uses the channel information (the output format, the Measurement mode and the input number) to process the analog sample. When conversion is complete, the result is stored in the result buffer for the specific analog input, and passed to the digital filter and digital comparator if they were configured to use data from this particular channel. The ADC provides each analog input the ability to specify its own trigger source. This capability allows the ADC to sample and convert analog inputs that are associated with PWM generators operating on independent time bases.

DS70005319B-page 259 dsPIC33CH128MP508 FAMILY NOTES: DS70005319B-page 260 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 4.0 SLAVE MODULES 4.1 Slave CPU Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "dsPIC33E Enhanced CPU" (DS70005158) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The Slave CPU fetches instructions from the PRAM (Program RAM Memory for the Slave). The Master core and Slave core can run independently asynchronously, at the same speed, or at a different speed. On a POR, the PRAM will not have the user code. The Master core will load the Slave code from the Master Flash to the Slave PRAM, and once the code is verified, the Master core will release the Slave core to start executing the code (SLVEN (MSI1CON<15> = 1). Note: All of the associated register names are the same on the Master as well as the Slave. The Slave code will be developed in a separate project in MPLAB(R) X IDE with the device selection, MP50XS1/20XS1, where S1 indicates the Slave device. The dsPIC33CH128MP508S1 family CPU has a 16-bit (data) modified Harvard architecture with an enhanced instruction set, including significant support for Digital Signal Processing (DSP). The CPU has a 24-bit instruction word with a variable length opcode field. The Program Counter (PC) is 23 bits wide and addresses up to 4M x 24 bits of user program memory space. 4.1.1 REGISTERS The dsPIC33CH128MP508S1 devices have sixteen, 16-bit Working registers in the programmer's model. Each of the Working registers can act as a data, address or address offset register. The 16th Working register (W15) operates as a Software Stack Pointer for interrupts and calls. In addition, the dsPIC33CH128MP508S1 devices include four Alternate Working register sets, which consist of W0 through W14. The Alternate Working registers can be made persistent to help reduce the saving and restoring of register content during Interrupt Service Routines (ISRs). The Alternate Working registers can be assigned to a specific Interrupt Priority Level (IPL1 through IPL7) by configuring the CTXTx<2:0> bits in the FALTREG Configuration register. The Alternate Working registers can also be accessed manually by using the CTXTSWP instruction. The CCTXI<2:0> and MCTXI<2:0> bits in the CTXTSTAT register can be used to identify the current and most recent, manually selected Working register sets. 4.1.2 INSTRUCTION SET The instruction set for dsPIC33CH128MP508S1 devices has two classes of instructions: the MCU class of instructions and the DSP class of instructions. These two instruction classes are seamlessly integrated into the architecture and execute from a single execution unit. The instruction set includes many addressing modes and was designed for optimum C compiler efficiency. Note 1: Unlike the Master, there is no prefetch of the instruction implemented for the Slave. Most instructions execute in a single-cycle effective execution rate, with the exception of instructions that change the program flow, the double-word move (MOV.D) instruction, PSV accesses and the table instructions. Overhead-free program loop constructs are supported using the DO and REPEAT instructions, both of which are interruptible at any point. 2017-2018 Microchip Technology Inc. DS70005319B-page 261 dsPIC33CH128MP508 FAMILY 4.1.3 DATA SPACE ADDRESSING The base Data Space can be addressed as up to 4K words or 8 Kbytes, and is split into two blocks, referred to as X and Y data memory. Each memory block has its own independent Address Generation Unit (AGU). The MCU class of instructions operates solely through the X memory AGU, which accesses the entire memory map as one linear Data Space. Certain DSP instructions operate through the X and Y AGUs to support dual operand reads, which splits the data address space into two parts. The X and Y Data Space boundary is device-specific. The upper 32 Kbytes of the Data Space memory map can optionally be mapped into Program Space (PS) at any 16K program word boundary. The program-to-Data Space mapping feature, known as Program Space Visibility (PSV), lets any instruction access Program Space as if it were Data Space. Refer to "Data Memory" (DS70595) in the "dsPIC33/PIC24 Family Reference Manual" for more details on PSV and table accesses. 4.1.4 ADDRESSING MODES The CPU supports these addressing modes: * * * * * * Inherent (no operand) Relative Literal Memory Direct Register Direct Register Indirect Each instruction is associated with a predefined addressing mode group, depending upon its functional requirements. As many as six addressing modes are supported for each instruction. On dsPIC33CH128MP508S1 family devices, overheadfree circular buffers (Modulo Addressing) are supported in both X and Y address spaces. The Modulo Addressing removes the software boundary checking overhead for DSP algorithms. The X AGU Circular Addressing can be used with any of the MCU class of instructions. The X AGU also supports BitReversed Addressing to greatly simplify input or output data re-ordering for radix-2 FFT algorithms.

Unless otherwise mentioned, arithmetic operations are two's complement in nature. Depending on the operation, the ALU can affect the values of the Carry (C), Zero (Z), Negative (N), Overflow (OV) and Digit Carry (DC) Status bits in the SR register. The C and DC Status bits operate as Borrow and Digit Borrow bits, respectively, for subtraction operations. The ALU can perform 8-bit or 16-bit operations, depending on the mode of the instruction that is used. Data for the ALU operation can come from the W register array or data memory, depending on the addressing mode of the instruction. Likewise, output data from the ALU can be written to the W register array or a data memory location. Refer to the "16-Bit MCU and DSC Programmer's Reference Manual" (DS70000157) for information on the SR bits affected by each instruction. The core CPU incorporates hardware support for both multiplication and division. This includes a dedicated hardware multiplier and support hardware for 16-bit divisor division. 4.1.8.1 Multiplier Using the high-speed, 17-bit x 17-bit multiplier, the ALU supports unsigned, signed or mixed-sign operation in several MCU Multiplication modes: * * * * * * * 16-bit x 16-bit signed 16-bit x 16-bit unsigned 16-bit signed x 5-bit (literal) unsigned 16-bit signed x 16-bit unsigned 16-bit unsigned x 5-bit (literal) unsigned 16-bit unsigned x 16-bit signed 8-bit unsigned x 8-bit unsigned 4.1.8.2 Divider 4.1.9 DSP ENGINE The DSP engine consists of a high-speed, 17-bit x 17-bit multiplier, a 40-bit barrel shifter and a 40-bit adder/ subtracter (with two target accumulators, round and saturation logic). The DSP engine can also perform inherent accumulatorto-accumulator operations that require no additional data. These instructions are, ADD, SUB and NEG. The DSP engine has options selected through bits in the CPU Core Control register (CORCON), as listed below: * * * * * * Fractional or integer DSP multiply (IF) Signed, unsigned or mixed-sign DSP multiply (USx) Conventional or convergent rounding (RND) Automatic saturation on/off for ACCA (SATA) Automatic saturation on/off for ACCB (SATB) Automatic saturation on/off for writes to data memory (SATDW) * Accumulator Saturation mode selection (ACCSAT) TABLE 4-2: Instruction DSP INSTRUCTIONS SUMMARY Algebraic Operation ACC Write-Back Yes CLR A=0 ED A = (x - y)2 No 2 EDAC A = A + (x - y) No MAC A = A + (x * y) Yes x2 No MAC A=A+ MOVSAC No change in A MPY A=x*y No MPY A = x2 No MPY.N A=-x*y No MSC A=A-x*y Yes Yes The divide block supports 32-bit/16-bit and 16-bit/16-bit signed and unsigned integer divide operations with the following data sizes: * * * * 32-bit signed/16-bit signed divide 32-bit unsigned/16-bit unsigned divide 16-bit signed/16-bit signed divide 16-bit unsigned/16-bit unsigned divide The quotient for all divide instructions ends up in W0 and the remainder in W1. 16-bit signed and unsigned DIV instructions can specify any W register for both the 16-bit divisor (Wn) and any W register (aligned) pair (W(m + 1):Wm) for the 32-bit dividend. The divide algorithm takes one cycle per bit of divisor, so both 32-bit/16-bit and 16-bit/16-bit instructions take the same number of cycles to execute. 2017-2018 Microchip Technology Inc. DS70005319B-page 271 dsPIC33CH128MP508 FAMILY 4.2 Slave Memory Organization Note: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "dsPIC33E/PIC24E Program Memory" (DS70000613) in the "dsPIC33/ PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The dsPIC33CH128MP508S1 family architecture features separate program and data memory spaces, and buses. This architecture also allows the direct access of program memory from the Data Space (DS) during code execution. FIGURE 4-3: 4.2.1 PROGRAM ADDRESS SPACE The program address memory space of the dsPIC33CH128MP508S1 family devices is 4M instructions. The space is addressable by a 24-bit value derived either from the 23-bit PC during program execution, or from table operation or Data Space remapping, as described in Section 4.2.8 "Interfacing Program and Data Memory Spaces". User application access to the program memory space is restricted to the lower half of the address range (0x000000 to 0x7FFFFF). The exception is the use of TBLRD operations, which use TBLPAG<7> to permit access to calibration data and Device ID sections of the configuration memory space. The PRAM for the Slave dsPIC33CH128MP508S1 devices implements two 12-Kbyte PRAM panels with a total of 24 Kbytes of PRAM available for the Slave device. All variants of the Slave have the same amount of PRAM available, irrespective of the size of the Flash available on the Master Flash program memory, as shown in Figure 4-3.

DS70005319B-page 272 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 4.2.1.1 Program Memory Organization 4.2.1.2 The program memory space is organized in wordaddressable blocks. Although it is treated as 24 bits wide, it is more appropriate to think of each address of the program memory as a lower and upper word, with the upper byte of the upper word being unimplemented. The lower word always has an even address, while the upper word has an odd address (Figure 4-4). All dsPIC33CH128MP508S1 family devices reserve the addresses between 0x000000 and 0x000200 for hard-coded program execution vectors. A hardware Reset vector is provided to redirect code execution from the default value of the PC on device Reset to the actual start of code. A GOTO instruction is programmed by the user application at address, 0x000000, of PRAM memory, with the actual address for the start of code at address, 0x000200, of Flash memory. Program memory addresses are always word-aligned on the lower word, and addresses are incremented, or decremented, by two, during code execution. This arrangement provides compatibility with data memory space addressing and makes data in the program memory space accessible. FIGURE 4-4: msw Address A more detailed discussion of the Interrupt Vector Tables (IVTs) is provided in Table 4-20.

The Data Space is accessed using separate Address Generation Units (AGUs) for read and write operations. The data memory map is shown in Figure 4-5. All Effective Addresses (EAs) in the data memory space are 16 bits wide and point to bytes within the Data Space. This arrangement gives a base Data Space address range of 64 Kbytes or 32K words. The lower half of the data memory space (i.e., when EA<15> = 0) is used for implemented memory addresses, while the upper half (EA<15> = 1) is reserved for the Program Space Visibility (PSV). The dsPIC33CH128MP508S1 family devices implement up to 4 Kbytes of data memory. If an EA points to a location outside of this area, an all-zero word or byte is returned. 4.2.2.1 Data Space Width The data memory space is organized in byteaddressable, 16-bit wide blocks. Data is aligned in data memory and registers as 16-bit words, but all Data Space EAs resolve to bytes. The Least Significant Bytes (LSBs) of each word have even addresses, while the Most Significant Bytes (MSBs) have odd addresses. 4.2.2.2 Data Memory Organization and Alignment To maintain backward compatibility with PIC (R) MCU devices and improve Data Space memory usage efficiency, the dsPIC33CH128MP508S1 family instruction set supports both word and byte operations. As a consequence of byte accessibility, all Effective Address calculations are internally scaled to step through wordaligned memory. For example, the core recognizes that Post-Modified Register Indirect Addressing mode [Ws++] results in a value of Ws + 1 for byte operations and Ws + 2 for word operations. A data byte read, reads the complete word that contains the byte, using the LSb of any EA to determine which byte to select. The selected byte is placed onto the LSB of the data path. That is, data memory and registers are organized as two parallel, byte-wide entities with shared (word) address decode, but separate write lines. Data byte writes only write to the corresponding side of the array or register that matches the byte address. DS70005319B-page 274 All word accesses must be aligned to an even address. Misaligned word data fetches are not supported, so care must be taken when mixing byte and word operations, or translating from 8-bit MCU code. If a misaligned read or write is attempted, an address error trap is generated. If the error occurred on a read, the instruction underway is completed. If the error occurred on a write, the instruction is executed but the write does not occur. In either case, a trap is then executed, allowing the system and/or user application to examine the machine state prior to execution of the address Fault. All byte loads into any W register are loaded into the LSB; the MSB is not modified. A Sign-Extend (SE) instruction is provided to allow user applications to translate 8-bit signed data to 16-bit signed values. Alternatively, for 16-bit unsigned data, user applications can clear the MSB of any W register by executing a Zero-Extend (ZE) instruction on the appropriate address. 4.2.2.3 SFR Space The first 4 Kbytes of the Near Data Space, from 0x0000 to 0x0FFF, is primarily occupied by Special Function Registers (SFRs). These are used by the dsPIC33CH128MP508S1 family core and peripheral modules for controlling the operation of the device. SFRs are distributed among the modules that they control and are generally grouped together by module. Much of the SFR space contains unused addresses; these are read as `0'. Note: 4.2.2.4 The actual set of peripheral features and interrupts varies by the device. Refer to the corresponding device tables and pinout diagrams for device-specific information. Near Data Space The 8-Kbyte area, between 0x0000 and 0x1FFF, is referred to as the Near Data Space. Locations in this space are directly addressable through a 13-bit absolute address field within all memory direct instructions. Additionally, the whole Data Space is addressable using MOV instructions, which support Memory Direct Addressing mode with a 16-bit address field, or by using Indirect Addressing mode using a Working register as an Address Pointer. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY FIGURE 4-5: DATA MEMORY MAP FOR SLAVE dsPIC33CH128MP508S1 DEVICES MSB Address MSB 4-Kbyte SFR Space LSB Address 16 Bits LSB 0x0001 0x0000 SFR Space 0x0FFE 0x1000 0x0FFF 0x1001 X Data RAM (X) (2K) 4-Kbyte SRAM Space 0x1800 0x1802 0x17FE 0x1801 8-Kbyte Near Data Space Y Data RAM (Y) (2K) 0x1FFF 0x2001 0x1FFE 0x2000 0x8001 0x8000 X Data Unimplemented (X) 0xFFFF Note: Optionally Mapped into Program Memory 0xFFFE Memory areas are not shown to scale. 2017-2018 Microchip Technology Inc. DS70005319B-page 275 dsPIC33CH128MP508 FAMILY 4.2.2.5 X and Y Data Spaces The dsPIC33CH128MP508S1 family core has two Data Spaces, X and Y. These Data Spaces can be considered either separate (for some DSP instructions) or as one unified linear address range (for MCU instructions). The Data Spaces are accessed using two Address Generation Units (AGUs) and separate data paths. This feature allows certain instructions to concurrently fetch two words from RAM, thereby enabling efficient execution of DSP algorithms, such as Finite Impulse Response (FIR) filtering and Fast Fourier Transform (FFT). The X Data Space is used by all instructions and supports all addressing modes. X Data Space has separate read and write data buses. The X read data bus is the read data path for all instructions that view Data Space as combined X and Y address space. It is also the X data prefetch path for the dual operand DSP instructions (MAC class). 4.2.3 MEMORY RESOURCES Many useful resources are provided on the main product page of the Microchip web site for the devices listed in this data sheet. This product page contains the latest updates and additional information. 4.2.3.1 Key Resources * "dsPIC33E/PIC24E Program Memory" (DS70000613) in the "dsPIC33/PIC24 Family Reference Manual" * Code Samples * Application Notes * Software Libraries * Webinars * All Related "dsPIC33/PIC24 Family Reference Manual" Sections * Development Tools The Y Data Space is used in concert with the X Data Space by the MAC class of instructions (CLR, ED, EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide two concurrent data read paths. Both the X and Y Data Spaces support Modulo Addressing mode for all instructions, subject to addressing mode restrictions. Bit-Reversed Addressing mode is only supported for writes to X Data Space. All data memory writes, including in DSP instructions, view Data Space as combined X and Y address space. The boundary between the X and Y Data Spaces is device-dependent and is not user-programmable.

DS70005319B-page 285 dsPIC33CH128MP508 FAMILY 4.2.4.1 Paged Memory Scheme The paged memory scheme provides access to multiple 32-Kbyte windows in the PSV memory. The Data Space Read Page (DSRPAG) register, in combination with the upper half of the Data Space address, can provide up to 8 Mbytes of PSV address space. The paged data memory space is shown in Figure 4-7. The dsPIC33CH128MP508S1 architecture extends the available Data Space through a paging scheme, which allows the available Data Space to be accessed using MOV instructions in a linear fashion for pre- and post-modified Effective Addresses (EAs). The upper half of the base Data Space address is used in conjunction with the Data Space Read Page (DSRPAG) register to form the Program Space Visibility (PSV) address. The Program Space (PS) can be accessed with a DSRPAG of 0x200 or greater. Only reads from PS are supported using the DSRPAG. The Data Space Read Page (DSRPAG) register is located in the SFR space. Construction of the PSV address is shown in Figure 4-6. When DSRPAG<9> = 1 and the base address bit, EA<15> = 1, the DSRPAG<8:0> bits are concatenated onto EA<14:0> to form the 24-bit PSV read address.

An overflow or underflow of the EA in the PSV pages can occur at the page boundaries when: * The initial address, prior to modification, addresses the PSV page * The EA calculation uses Pre- or Post-Modified Register Indirect Addressing; however, this does not include Register Offset Addressing In general, when an overflow is detected, the DSRPAG register is incremented and the EA<15> bit is set to keep the base address within the PSV window. When an underflow is detected, the DSRPAG register is decremented and the EA<15> bit is set to keep the TABLE 4-16: O, Read [++Wn] or [Wn++] U, Read U, Read U, Read [--Wn] or [Wn--] Legend: Note 1: 2: 3: 4: Exceptions to the operation described above arise when entering and exiting the boundaries of Page 0 and PSV spaces.

An EDS access, with DSRPAG = 0x000, will generate an address error trap. Only reads from PS are supported using DSRPAG. Pseudolinear Addressing is not supported for large offsets. DS70005319B-page 288 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY Extended X Data Space The lower portion of the base address space range, between 0x0000 and 0x7FFF, is always accessible, regardless of the contents of the Data Space Read Page register. It is indirectly addressable through the register indirect instructions. It can be regarded as being located in the default EDS Page 0 (i.e., EDS address range of 0x000000 to 0x007FFF with the base address bit, EA<15> = 0, for this address range). However, Page 0 cannot be accessed through the upper 32 Kbytes, 0x8000 to 0xFFFF, of base Data Space in combination with DSRPAG = 0x00. Consequently, DSRPAG is initialized to 0x001 at Reset. Note 1: DSRPAG should not be used to access Page 0. An EDS access with DSRPAG set to 0x000 will generate an address error trap. 2: Clearing the DSRPAG in software has no effect. The remaining PSV pages are only accessible using the DSRPAG register in combination with the upper 32 Kbytes, 0x8000 to 0xFFFF, of the base address, where base address bit, EA<15> = 1. 4.2.4.3 When the PC is pushed onto the stack, PC<15:0> are pushed onto the first available stack word, then PC<22:16> are pushed into the second available stack location. For a PC push during any CALL instruction, the MSB of the PC is zero-extended before the push, as shown in Figure 4-8. During exception processing, the MSB of the PC is concatenated with the lower 8 bits of the CPU STATUS Register, SR. This allows the contents of SRL to be preserved automatically during interrupt processing. Note 1: To maintain system Stack Pointer (W15) coherency, W15 is never subject to (EDS) paging, and is therefore, restricted to an address range of 0x0000 to 0xFFFF. The same applies to W14 when used as a Stack Frame Pointer (SFA = 1). 2: As the stack can be placed in, and can access X and Y spaces, care must be taken regarding its use, particularly with regard to local automatic variables in a C development environment Software Stack The W15 register serves as a dedicated Software Stack Pointer (SSP), and is automatically modified by exception processing, subroutine calls and returns; however, W15 can be referenced by any instruction in the same manner as all other W registers. This simplifies reading, writing and manipulating the Stack Pointer (for example, creating stack frames). Note: The Software Stack Pointer always points to the first available free word and fills the software stack, working from lower toward higher addresses. Figure 4-8 illustrates how it pre-decrements for a stack pop (read) and post-increments for a stack push (writes). To protect against misaligned stack accesses, W15<0> is fixed to `0' by the hardware. W15 is initialized to 0x1000 during all Resets. This address ensures that the SSP points to valid RAM in all dsPIC33CH128MP508S1 devices and permits stack availability for non-maskable trap exceptions. These can occur before the SSP is initialized by the user software. You can reprogram the SSP during initialization to any location within Data Space. 2017-2018 Microchip Technology Inc.

The addressing modes provided in the MAC class of instructions differ from those in the other instruction types. 4.2.5.1 File Register Instructions Most file register instructions use a 13-bit address field (f) to directly address data present in the first 8192 bytes of data memory (Near Data Space). Most file register instructions employ a Working register, W0, which is denoted as WREG in these instructions. The destination is typically either the same file register or WREG (with the exception of the MUL instruction), which writes the result to a register or register pair. The MOV instruction allows additional flexibility and can access the entire Data Space. TABLE 4-17: 4.2.5.2 MCU Instructions The three-operand MCU instructions are of the form: Operand 3 = Operand 1 <function> Operand 2 where Operand 1 is always a Working register (that is, the addressing mode can only be Register Direct), which is referred to as Wb. Operand 2 can be a W register fetched from data memory or a 5-bit literal. The result location can either be a W register or a data memory location. The following addressing modes are supported by MCU instructions: * * * * * Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified 5-Bit or 10-Bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions can support different subsets of these addressing modes. FUNDAMENTAL ADDRESSING MODES SUPPORTED Addressing Mode File Register Direct Description The address of the file register is specified explicitly. Register Direct The contents of a register are accessed directly. Register Indirect The contents of Wn form the Effective Address (EA). Register Indirect Post-Modified The contents of Wn form the EA. Wn is post-modified (incremented or decremented) by a constant value. Register Indirect Pre-Modified Wn is pre-modified (incremented or decremented) by a signed constant value to form the EA. Register Indirect with Register Offset The sum of Wn and Wb forms the EA. (Register Indexed) Register Indirect with Literal Offset DS70005319B-page 290 The sum of Wn and a literal forms the EA. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 4.2.5.3 Move and Accumulator Instructions Move instructions, and the DSP accumulator class of instructions, provide a greater degree of addressing flexibility than other instructions. In addition to the addressing modes supported by most MCU instructions, move and accumulator instructions also support Register Indirect with Register Offset Addressing mode, also referred to as Register Indexed mode. Note: For the MOV instructions, the addressing mode specified in the instruction can differ for the source and destination EA. However, the 4-bit Wb (Register Offset) field is shared by both source and destination (but typically only used by one). 4.2.5.4 The dual source operand DSP instructions (CLR, ED, EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), also referred to as MAC instructions, use a simplified set of addressing modes to allow the user application to effectively manipulate the Data Pointers through register indirect tables. The two-source operand prefetch registers must be members of the set {W8, W9, W10, W11}. For data reads, W8 and W9 are always directed to the X RAGU, and W10 and W11 are always directed to the Y AGU. The Effective Addresses generated (before and after modification) must therefore, be valid addresses within X Data Space for W8 and W9, and Y Data Space for W10 and W11. Note: In summary, the following addressing modes are supported by move and accumulator instructions: * * * * * * * * Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified Register Indirect with Register Offset (Indexed) Register Indirect with Literal Offset 8-Bit Literal 16-Bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions may support different subsets of these addressing modes. 2017-2018 Microchip Technology Inc. MAC Instructions Register Indirect with Register Offset Addressing mode is available only for W9 (in X space) and W11 (in Y space). In summary, the following addressing modes are supported by the MAC class of instructions: * * * * * Register Indirect Register Indirect Post-Modified by 2 Register Indirect Post-Modified by 4 Register Indirect Post-Modified by 6 Register Indirect with Register Offset (Indexed) 4.2.5.5 Other Instructions Besides the addressing modes outlined previously, some instructions use literal constants of various sizes. For example, BRA (branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the DISI instruction uses a 14-bit unsigned literal field. In some instructions, such as ULNK, the source of an operand or result is implied by the opcode itself. Certain operations, such as a NOP, do not have any operands. DS70005319B-page 291 dsPIC33CH128MP508 FAMILY 4.2.6 MODULO ADDRESSING 4.2.6.1 Modulo Addressing mode is a method of providing an automated means to support circular data buffers using hardware. The objective is to remove the need for software to perform data address boundary checks when executing tightly looped code, as is typical in many DSP algorithms. Start and End Address The Modulo Addressing scheme requires that a starting and ending address be specified and loaded into the 16-bit Modulo Buffer Address registers: XMODSRT, XMODEND, YMODSRT and YMODEND (see Table 4-1). Note: Y space Modulo Addressing EA calculations assume word-sized data (LSb of every EA is always clear). Modulo Addressing can operate in either Data or Program Space (since the Data Pointer mechanism is essentially the same for both). One circular buffer can be supported in each of the X (which also provides the pointers into Program Space) and Y Data Spaces. Modulo Addressing can operate on any W Register Pointer. However, it is not advisable to use W14 or W15 for Modulo Addressing since these two registers are used as the Stack Frame Pointer and Stack Pointer, respectively. The length of a circular buffer is not directly specified. It is determined by the difference between the corresponding start and end addresses. The maximum possible length of the circular buffer is 32K words (64 Kbytes). In general, any particular circular buffer can be configured to operate in only one direction, as there are certain restrictions on the buffer start address (for incrementing buffers) or end address (for decrementing buffers), based upon the direction of the buffer. The Modulo and Bit-Reversed Addressing Control register, MODCON<15:0>, contains enable flags, as well as a W register field to specify the W Address registers. The XWM and YWM fields select the registers that operate with Modulo Addressing: The only exception to the usage restrictions is for buffers that have a power-of-two length. As these buffers satisfy the start and end address criteria, they can operate in a Bidirectional mode (that is, address boundary checks are performed on both the lower and upper address boundaries). * If XWM = 1111, X RAGU and X WAGU Modulo Addressing is disabled * If YWM = 1111, Y AGU Modulo Addressing is disabled 4.2.6.2 W Address Register Selection The X Address Space Pointer W (XWM) register, to which Modulo Addressing is to be applied, is stored in MODCON<3:0> (see Table 4-1). Modulo Addressing is enabled for X Data Space when XWM is set to any value other than `1111' and the XMODEN bit is set (MODCON<15>). The Y Address Space Pointer W (YWM) register, to which Modulo Addressing is to be applied, is stored in MODCON<7:4>. Modulo Addressing is enabled for Y Data Space when YWM is set to any value other than `1111' and the YMODEN bit (MODCON<14>) is set.

Address boundaries check for addresses equal to: * The upper boundary addresses for incrementing buffers * The lower boundary addresses for decrementing buffers It is important to realize that the address boundaries check for addresses less than, or greater than, the upper (for incrementing buffers) and lower (for decrementing buffers) boundary addresses (not just equal to). Address changes can, therefore, jump beyond boundaries and still be adjusted correctly. Note: 4.2.7 The modulo corrected Effective Address is written back to the register only when Pre-Modify or Post-Modify Addressing mode is used to compute the Effective Address. When an address offset (such as [W7 + W2]) is used, Modulo Addressing correction is performed, but the contents of the register remain unchanged. BIT-REVERSED ADDRESSING Bit-Reversed Addressing mode is intended to simplify data reordering for radix-2 FFT algorithms. It is supported by the X AGU for data writes only. The modifier, which can be a constant value or register contents, is regarded as having its bit order reversed. The address source and destination are kept in normal order. Thus, the only operand requiring reversal is the modifier. 4.2.7.1 Bit-Reversed Addressing Implementation Bit-Reversed Addressing mode is enabled in any of these situations: * BWMx bits (W register selection) in the MODCON register are any value other than `1111' (the stack cannot be accessed using Bit-Reversed Addressing) * The BREN bit is set in the XBREV register * The addressing mode used is Register Indirect with Pre-Increment or Post-Increment If the length of a bit-reversed buffer is M = 2N bytes, the last `N' bits of the data buffer start address must be zeros. XB<14:0> is the Bit-Reversed Addressing modifier, or `pivot point', which is typically a constant. In the case of an FFT computation, its value is equal to half of the FFT data buffer size. Note: All bit-reversed EA calculations assume word-sized data (LSb of every EA is always clear). The XB value is scaled accordingly to generate compatible (byte) addresses. When enabled, Bit-Reversed Addressing is executed only for Register Indirect with Pre-Increment or PostIncrement Addressing and word-sized data writes. It does not function for any other addressing mode or for byte-sized data and normal addresses are generated instead. When Bit-Reversed Addressing is active, the W Address Pointer is always added to the address modifier (XB) and the offset associated with the Register Indirect Addressing mode is ignored. In addition, as word-sized data is a requirement, the LSb of the EA is ignored (and always clear). Note: Modulo Addressing and Bit-Reversed Addressing can be enabled simultaneously using the same W register, but BitReversed Addressing operation will always take precedence for data writes when enabled. If Bit-Reversed Addressing has already been enabled by setting the BREN (XBREV<15>) bit, a write to the XBREV register should not be immediately followed by an indirect read operation using the W register that has been designated as the Bit-Reversed Pointer. 2017-2018 Microchip Technology Inc.

This capability makes the method ideal for accessing data tables that need to be updated periodically. It also allows access to all bytes of the program word. The remapping method allows an application to access a large block of data on a read-only basis, which is ideal for look-ups from a large table of static data. However, this method only provides visibility to the lower 16 bits in each location addressed. The dsPIC33CH128MP508S1 family architecture uses a 24-bit wide Program Space (PS) and a 16-bit wide Data Space (DS). The architecture is also a modified Harvard scheme, meaning that data can also be present in the Program Space. To use this data successfully, it must be accessed in a way that preserves the alignment of information in both spaces. Aside from normal execution, the architecture of the dsPIC33CH128MP508S1 family devices provides two methods by which Program Space can be accessed during operation: * Using table instructions to access individual bytes or words anywhere in the Program Space * Remapping a portion of the Program Space into the Data Space (Program Space Visibility) TABLE 4-19: PROGRAM SPACE ADDRESS CONSTRUCTION Instruction Access (Code Execution) User TBLRD/TBLWT (Byte/Word Read/Write) User FIGURE 4-11: Program Space Address Access Space Access Type <23> <22:16> <15> <14:1> <0> PC<22:1> 0 0 0xxx xxxx xxxx xxxx xxxx xxx0 TBLPAG<7:0> Data EA<15:0> 0xxx xxxx xxxx xxxx xxxx xxxx DATA ACCESS FROM PROGRAM SPACE ADDRESS GENERATION Program Counter(1) Program Counter 0 0 23 Bits EA Table Operations(2) 1/0 TBLPAG 1/0 8 Bits 16 Bits 24 Bits User/Configuration Space Select Note 1: 2: Byte Select The Least Significant bit (LSb) of Program Space addresses is always fixed as `0' to maintain word alignment of data in the Program and Data Spaces. Table operations are not required to be word-aligned. Table Read operations are permitted in the configuration memory space. 2017-2018 Microchip Technology Inc. DS70005319B-page 295 dsPIC33CH128MP508 FAMILY 4.2.8.1 Data Access from Program Memory Using Table Instructions The TBLRDL and TBLWTL instructions offer a direct method of reading or writing the lower word of any address within the Program Space without going through Data Space. The TBLRDH and TBLWTH instructions are the only method to read or write the upper eight bits of a Program Space word as data. This allows program memory addresses to directly map to Data Space addresses. Program memory can thus be regarded as two 16-bit wide word address spaces, residing side by side, each with the same address range. TBLRDL and TBLWTL access the space that contains the least significant data word. TBLRDH and TBLWTH access the space that contains the upper data byte. Two table instructions are provided to read byte or word-sized (16-bit) data from Program Space. Both function as either byte or word operations. * TBLRDL (Table Read Low): - In Word mode, this instruction maps the lower word of the Program Space location (P<15:0>) to a data address (D<15:0>). - In Byte mode, either the upper or lower byte of the lower program word is mapped to the lower byte of a data address. The upper byte is selected when Byte Select is `1'; the lower byte is selected when it is `0'. FIGURE 4-12: * TBLRDH (Table Read High): - In Word mode, this instruction maps the entire upper word of a program address (P<23:16>) to a data address. The `phantom' byte (D<15:8>) is always `0'. - In Byte mode, either the upper or lower byte of the upper program word is mapped to the lower byte of a data address. The upper byte is selected when Byte Select is `1'; the lower byte is selected when it is `0'. When the upper byte is selected, the `phantom' byte is read as `0'. In a similar fashion, two table instructions, TBLWTH and TBLWTL, are used to write individual bytes or words to a Program Space address. For these writes, data is written to a set of NVM latches and subsequently copied to the Program Space address using an NVM write operation. The details of their operation are explained in Section 4.3.2 "RTSP Operation".

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Dual Partition Flash Program Memory" (DS70005156) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com) 2: Though the reference to the chapter is "Dual Partition Flash Program Memory" (DS70005156), the program memory for the Slave code is PRAM. Therefore, after each POR, the Master will have to reload the content of the Slave PRAM. The dsPIC33CH128MP508S1 family devices contain internal PRAM program memory for storing and executing application code. The PRAM program memory array is organized into rows of 128 instructions or 64 double instruction words. Though the PRAM is volatile, it is writable during normal operation over the entire VDD range. PRAM memory can be programmed in three ways: * In-Circuit Serial ProgrammingTM (ICSPTM) * Run-Time Self-Programming (RTSP) * Master to Slave Image Loading (MSIL) ICSP allows for a dsPIC33CH128MP508S1 family device to be serially programmed in the application circuit. Since the Slave PRAM is volatile, Slave PRAM ICSP programming is supported only as a development and debugging feature. RTSP allows the Slave PRAM user application code to update itself during run time. This feature is capable of writing a single program memory word (two instructions) or an entire row as needed. Master to Slave Image Loading allows the Master user code to load the Slave PRAM at run time. A Slave PRAM compatible image is stored in Master Flash memory. At run time, the Master user code is responsible for loading and verifying the contents of the Slave PRAM. 2017-2018 Microchip Technology Inc. Note: 4.3.1 In an actual application mode, the Slave PRAM is loaded by the Master, so the ICSP mode of PRAM operation is valid only for the Debug mode during the code development. PRAM PROGRAMMING OPERATIONS For ICSP and RTSP programming of the Slave PRAM, TBLWTL and TBLWTH instructions are used to write to the NVM write latches. An NVM write operation then writes the contents of both latches to the PRAM, starting at the address defined in the NVMADR and NVMADRU registers. For Master to Slave Image Loading (MSIL) of the Slave PRAM, the Master user code is responsible for transferring the Slave image contents stored in the Master Flash to the Slave PRAM. The LDSLV instruction is used along with the DSRPAG and DSWPAG registers to transfer a single 24-bit instruction to the Slave PRAM. The VFSLV instruction allows the Master user code to verify that the PRAM has been loaded correctly. Note: Master to Slave Image Loading is the only supported method for programming the Slave PRAM in a final user application. Regardless of the method used to program the PRAM, a few basic requirements should be met: * A full 48-bit double instruction word should always be programmed to a PRAM location. Either instruction may simply be a NOP to fulfill this requirement. This ensures a valid ECC value is generated for each pair of instructions written. * Assuming the above step is followed, the last 24-bit location in implemented program space, or prior to any unprogrammed region in program space, should never be executed. The penultimate instruction in either case must contain a program flow change instruction, such as a RETURN or a BRA instruction.

The double instruction word write blocks and single row write blocks are edge-aligned, from the beginning of program memory, on boundaries of one double instruction word and 64 double instruction words, respectively. Note: Because the PRAM is volatile, RTSP writes that change the Slave PRAM user code will be lost when the device is powered down. For persistent changes to Slave PRAM user code, the Slave image in the Master Flash should be updated. EXAMPLE 4-1: The basic sequence for RTSP programming is to first load two 24-bit instructions into the NVM write latches found in configuration memory space. Refer to Figure 4-3 for write latch addresses. Then, the WR bit in the NVMCON register is set to initiate the write process. The processor stalls (waits) until the programming operation is finished. The WR bit is automatically cleared when the operation is finished. All program operations may optionally use the NVM interrupt to signal the successful completion of the operation. Double instruction word writes are performed by manually loading both write latches, using TBLWTL and TBLWTH instructions, and then initiating the NVM write while the NVMOP<3:0> bits (NVMCON<3:0>) are set to `0x1'. The program space destination address is defined by the NVMADR/U registers. PRAM WRITE/READ //Sample code for PRAM write // Writing 0x777777 to location 0x3000 NVMCON = 0x4001; TBLPAG = 0xFA; // write latch upper address NVMADR = 0x3000; // set target write address of general segment NVMADRU = 0x0000; __builtin_tblwtl(0, 0x7777); // load write latches __builtin_tblwth (0,0x77); __builtin_tblwtl(2, 0x7777); __builtin_tblwth (2,0x77); // load write latches asm volatile ("disi #5"); __builtin_write_NVM(); while(_WR == 1 ) ; // Sample code for reading address location 0x3000 //readDataL /readDataLH need to be defined as variables. TBLPAG = 0x0000; readDataL = __builtin_tblrdl(0x3000); readDataH = __builtin_tblrdh(0x0000); 2017-2018 Microchip Technology Inc. DS70005319B-page 299 dsPIC33CH128MP508 FAMILY Row programming is performed by first loading 128 instructions into data RAM and then loading the address of the first instruction in that row into the NVMSRCADRL/H register. Once the write has been initiated, the device will automatically load two instructions into the write latches, and write them to the program space destination address defined by the NVMADR/U registers. The operation will increment the NVMSRCADRL/H and the NVMADR/U registers until all double instruction words have been programmed. The RPDF bit (NVMCON<9>) selects the format of the stored data in RAM to be either compressed or uncompressed. See Figure 4-14 for data formatting. Compressed data helps to reduce the amount of required RAM by using the upper byte of the second word for the MSB of the second instruction. FIGURE 4-14: UNCOMPRESSED/ COMPRESSED FORMAT 15 0 7 Increasing Address LSW1 0x00 Even Byte Address MSB1 LSW2 0x00 MSB2 UNCOMPRESSED FORMAT (RPDF = 0) Increasing Address 15 0 7 LSW1 MSB2 Even Byte Address MSB1 LSW2 COMPRESSED FORMAT (RPDF = 1) 4.3.3 MASTER TO SLAVE IMAGE LOADING (MSIL) Master to Slave Image Loading allows the Master user application code to transfer the Slave image stored in the Master Flash to the Slave PRAM. This is the only supported method for programming the Slave PRAM in a final user application. The LDSLV instruction is executed by the Master user application to transfer a single 24-bit instruction from the Master Flash address, defined by Ws<14:0> (DSRPAG), to the Slave PRAM address, defined by Wd<14:0> (DSWPAG). The LDSLV instruction should be executed in pairs to ensure correct ECC value generation for each double instruction word that is loaded into the Slave PRAM. The Slave image instruction found at a given even address should be loaded first. This will be the lower instruction word of a 48-bit double instruction word. The upper instruction word should then be loaded from the following odd address. After the pair of LDSLV instructions is executed by the Master user application, both 24-bit Slave image instructions and the generated 7-bit ECC value are actually loaded into the PRAM destination address locations. The VFSLV instruction allows the Master user application to verify that the PRAM has been loaded correctly. The VFSLV instruction compares the 24-bit instruction word stored in the Master Flash address, defined by Ws<14:0> (DSRPAG), to the 24 bit instruction written to the Slave PRAM address, defined by Wd<14:0> (DSWPAG). The VFSLV instruction should also be executed in pairs. The lower instruction word found on a given even address should be verified first. The upper instruction word found in the following odd address should then be verified. Then, the Slave image instruction pair read from the Master Flash will have a valid generated ECC value. This full double instruction word with ECC is then compared to the 55-bit value that was actually loaded into the PRAM destination locations. The entire Slave image may be loaded into the PRAM first and then subsequently verified. To make this process simpler, the Microchip libpic30.h library has implemented a routine which can be called once to either load or verify the entire Slave image. The __program_slave(core#, verify, &slave_image) routine uses the "verify" parameter to determine if the routine will run using LDSLV instructions or VFSLV instructions. A `0' will load the entire Slave image to the PRAM and a `1' will verify the entire Slave image in the PRAM. An example of how this routine may be used to load and verify the contents of the Slave PRAM is shown in Example 4-2. DS70005319B-page 300 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY EXAMPLE 4-2: SLAVE PRAM LOAD AND VERIFY ROUTINE #include <libpic30.h> //__program_slave(core#, verify, &slave_image) if (__program_slave(1, 0, &slave) == 0) { /* now verify */ if (__program_slave(1, 1, &slave) == ESLV_VERIFY_FAIL) { asm("reset"); // try again } } The __program_slave(core#, verify, &slave_image) routine only supports Slave images created with a compatible Microchip language tools format. Slave PRAM images not following this format will require a custom routine that follows all requirements for the PRAM Master to Slave image loading process described in this chapter. 4.3.4 PRAM DUAL PARTITION CONSIDERATIONS For dsPIC33CH128MP508S1 family devices operating in Dual Partition PRAM Program Memory modes, both partitions would be loaded using the Master to Slave image loading process. The Master can load the active partition of the PRAM only when SLVEN = 0 (Slave is not running). The Master can load the PRAM Inactive Partition any time. To support LiveUpdate, the Master would load the PRAM Inactive Partition while the Slave is running and then the Slave would execute the BOOTSWP instruction to swap partitions. 4.3.4.1 PRAM Partition Swapping At device Reset, the default PRAM partition is Partition 1. The BOOTSWP instruction provides the means of swapping the Active and Inactive Partitions (soft swap) without the need for a device Reset. The BOOTSWP must always be followed by a GOTO instruction. The BOOTSWP instruction swaps the Active and Inactive Partitions, and the PC vectors to the location specified by the GOTO instruction in the newly Active Partition. 2017-2018 Microchip Technology Inc. It is important to note that interrupts should temporarily be disabled while performing the soft swap sequence, and that after the partition swap, all peripherals and interrupts which were enabled remain enabled. Additionally, the RAM and stack will maintain their state after the switch. As a result, it is recommended that applications using soft swaps jump to a routine that will reinitialize the device in order to ensure the firmware runs as expected. The Configuration registers will have no effect during a soft swap. For robustness of operation, in order to execute the BOOTSWP instruction, it is necessary to execute the NVM unlocking sequence as follows: 1. 2. 3. Write 0x55 to NVMKEY. Write 0xAA to NVMKEY. Execute the BOOTSWP instruction. If the unlocking sequence is not performed, the BOOTSWP instruction will be executed as a forced NOP and a GOTO instruction, following the BOOTSWP instruction, will be executed, causing the PC to jump to that location in the current operating partition. The SFTSWP and P2ACTIV bits in the NVMCON register are used to determine a successful swap of the Active and Inactive Partitions, as well as which partition is active. After the BOOTSWP and GOTO instructions, the SFTSWP bit should be polled to verify the partition swap has occurred and then cleared for the next panel swap event. 4.3.4.2 Dual Partition Modes While operating in Dual Partition mode, the dsPIC33CH128MP508S1 family devices have the option for both partitions to have their own defined security segments, as shown in Figure . Alternatively, the device can operate in Protected Dual Partition mode, where Partition 1 becomes permanently write-protected. Protected Dual Partition mode allows for a "Factory Default" mode, which provides a fail-safe backup image to be stored in Partition 1. DS70005319B-page 301 dsPIC33CH128MP508 FAMILY 4.3.5 ERROR CORRECTING CODE (ECC) In order to improve program memory performance and durability, the devices include Error Correcting Code (ECC) functionality as an integral part of the PRAM memory controller. ECC can determine the presence of single bit errors in program data, including which bit is in error, and correct the data automatically without user intervention. ECC cannot be disabled. When data is written to program memory, ECC generates a 7-bit Hamming code parity value for every two (24-bit) instruction words. The data is stored in blocks of 48 data bits and seven parity bits; parity data is not memory-mapped and is inaccessible. When the data is read back, the ECC calculates the parity on it and compares it to the previously stored parity value. If a parity mismatch occurs, there are two possible outcomes: * Single bit error has occurred and has been automatically corrected on readback. * Double-bit error has occurred and the read data is not changed. Single bit error occurrence can be identified by the state of the ECCSBEIF bit (IFS0<13>). An interrupt can be generated when the corresponding interrupt enable bit is set, ECCSBEIE (IEC0<13>). The ECCSTATL register contains the parity information for single bit errors. The SECOUT<7:0> bits field contains the expected calculated SEC parity and the SECIN<7:0> bits contain the actual value from a PRAM read operation. The SECSYNDx bits (ECCSTATH<7:0>) indicate the bit position of the single bit error within the 48-bit pair of instruction words. When no error is present, SECINx equals SECOUTx and SECSYNDx is zero. Double-bit errors result in a generic hard trap. The ECCDBE bit (INTCON4<1>) will set to identify the source of the hard trap. If no Interrupt Service Routine is implemented for the hard trap, a device Reset will also occur. The ECCSTATH register contains double-bit error status information. The DEDOUT bit is the expected calculated DED parity and DEDIN is the actual value from a Flash read operation. When no error is present, DEDIN equals DEDOUT. 4.3.5.1 ECC FAULT INJECTION To test Fault handling, an EEC error can be generated. Both single and double-bit errors can be generated in both the read and write data paths. Read path Fault injection first reads the Flash data and then modifies it prior to entering the ECC logic. Write path Fault injection modifies the actual data prior to it being written into the target PRAM and will cause an EEC error on a subsequent Flash read. The following procedure is used to inject a Fault: 1. 2. 3. 4. 5. 6. Load the Flash target address into the ECCADDR register. Select 1st Fault bit determined by FLT1PTRx (ECCCONH<7:0>). The target bit is inverted to create the Fault. If a double Fault is desired, select the 2nd Fault bit determined by FLT2PTRx (ECCCONH<15:8>), otherwise set to all `1's. Write the NVMKEY unlock sequence. Enable the ECC Fault injection logic by setting FLTINJ bit (ECCCONL<0>). Perform a read or write to the Flash target address. 4.3.6 CONTROL REGISTERS Six SFRs are used to support ICSP and RTSP PRAM write operations: NVMCON, NVMKEY, NVMADR, NVMADRU, NVMSRCADRL and NVMSRCADRH. The NVMCON register (Register 4-4) selects the operation to be performed (double-word write or row write) and initiates the program cycle. NVMKEY (Register 4-7) is a write-only register that is used for write protection. To start a programming sequence, the user application must consecutively write 0x55 and 0xAA to the NVMKEY register. There are two NVM Address registers: NVMADRU and NVMADR. These two registers, when concatenated, form the 24-bit Effective Address (EA) of the selected word/row for programming operation. The NVMADRU register is used to hold the upper eight bits of the EA, while the NVMADR register is used to hold the lower 16 bits of the EA. For row programming (RTSP operation only), data to be written to the Slave PRAM is written into Slave data memory space (RAM) at an address defined by the NVMSRCADRL/H registers (location of first element in row programming data). For Master to Slave image loading, the DSRPAG and DSWPAG SFR registers are used in conjunction with the Ws and Wd Working registers to create the source and destination addresses for LDSLV and VFSLV instruction operations.

On system Reset, some of the registers associated with the CPU and peripherals are forced to a known Reset state, and some are unaffected. Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Reset" (DS70602) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). Note: All types of device Reset set a corresponding status bit in the RCON register to indicate the type of Reset (see Register 4-15). The Reset module combines all Reset sources and controls the device Master Reset Signal, SYSRST. The following is a list of device Reset sources: * * * * * * * * A POR clears all the bits, except for the BOR and POR bits (RCON<1:0>) that are set. The user application can set or clear any bit, at any time, during code execution. The RCON bits only serve as status bits. Setting a particular Reset status bit in software does not cause a device Reset to occur. POR: Power-on Reset BOR: Brown-out Reset MCLR: Master Clear Pin Reset SWR: RESET Instruction WDTO: Watchdog Timer Time-out Reset CM: Configuration Mismatch Reset TRAPR: Trap Conflict Reset IOPUWR: Illegal Condition Device Reset - Illegal Opcode Reset - Uninitialized W Register Reset - Security Reset The RCON register also has other bits associated with the Watchdog Timer and device power-saving states. The function of these bits is discussed in other sections of this data sheet. Note: The status bits in the RCON register should be cleared after they are read so that the next RCON register value after a device Reset is meaningful. For all Resets, the default clock source is determined by the FNOSC<2:0> bits in the FOSCSEL Configuration register. The value of the FNOSCx bits is loaded into the NOSC<2:0> (OSCCON<10:8>) bits on Reset, which in turn, initializes the system clock. A simplified block diagram of the Reset module is shown in Figure 4-15.

DS70005319B-page 313 dsPIC33CH128MP508 FAMILY 4.5 Slave Interrupt Controller Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Interrupts" (DS70000600) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The dsPIC33CH128MP508S1 family interrupt controller reduces the numerous peripheral interrupt request signals to a single interrupt request signal to the dsPIC33CH128MP508S1 family CPU. The interrupt controller has the following features: * Six Processor Exceptions and Software Traps * Seven User-Selectable Priority Levels * Interrupt Vector Table (IVT) with a Unique Vector for each Interrupt or Exception Source * Fixed Priority within a Specified User Priority Level * Fixed Interrupt Entry and Return Latencies Note: There is no Alternate Interrupt Vector Table (AIVT) for the Slave. 4.5.1 The dsPIC33CH128MP508S1 family Interrupt Vector Table (IVT), shown in Figure 4-16, resides in program memory, starting at location, 000004h. The IVT contains six non-maskable trap vectors and up to 246 sources of interrupts. In general, each interrupt source has its own vector. Each interrupt vector contains a 24-bit wide address. The value programmed into each interrupt vector location is the starting address of the associated Interrupt Service Routine (ISR). Interrupt vectors are prioritized in terms of their natural priority. This priority is linked to their position in the vector table. Lower addresses generally have a higher natural priority. For example, the interrupt associated with Vector 0 takes priority over interrupts at any other vector address. 4.5.2 RESET SEQUENCE A device Reset is not a true exception because the interrupt controller is not involved in the Reset process. The dsPIC33CH128MP508S1 family devices clear their registers in response to a Reset, which forces the PC to zero. The device then begins program execution at location, 0x000000. A GOTO instruction at the Reset address can redirect program execution to the appropriate start-up routine. Note: DS70005319B-page 314 INTERRUPT VECTOR TABLE Any unimplemented or unused vector locations in the IVT should be programmed with the address of a default interrupt handler routine that contains a RESET instruction. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY IVT Decreasing Natural Order Priority FIGURE 4-16: dsPIC33CH128MP508S1 FAMILY INTERRUPT VECTOR TABLE Reset - GOTO Instruction Reset - GOTO Address Oscillator Fail Trap Vector Address Error Trap Vector Generic Hard Trap Vector Stack Error Trap Vector Math Error Trap Vector Reserved Generic Soft Trap Vector Reserved Interrupt Vector 0 Interrupt Vector 1 : : : Interrupt Vector 52 Interrupt Vector 53 Interrupt Vector 54 : : : Interrupt Vector 116 Interrupt Vector 117 Interrupt Vector 118 Interrupt Vector 119 Interrupt Vector 120 : : : Interrupt Vector 244 Interrupt Vector 245 START OF CODE 0x000000 0x000002 0x000004 0x000006 0x000008 0x00000A 0x00000C 0x00000E 0x000010 0x000012 0x000014 0x000016 : : : 0x00007C 0x00007E 0x000080 : : : 0x0000FC 0x0000FE 0x000100 0x000102 0x000104 : : : 0x0001FC 0x0001FE 0x000200 See Table 4-20 for Interrupt Vector Details Note: In Dual Partition modes, each partition has a dedicated Interrupt Vector Table. 2017-2018 Microchip Technology Inc.

This product page contains the latest updates and additional information. 4.5.3.1 Key Resources * "Interrupts" (DS70000600) in the "dsPIC33/ PIC24 Family Reference Manual" * Code Samples * Application Notes * Software Libraries * Webinars * All Related "dsPIC33/PIC24 Family Reference Manual" Sections * Development Tools 4.5.4 INTERRUPT CONTROL AND STATUS REGISTERS The dsPIC33CH128MP508S1 family devices implement the following registers for the interrupt controller: * * * * * INTCON1 INTCON2 INTCON3 INTCON4 INTTREG 4.5.4.1 Global interrupt control functions are controlled from INTCON1, INTCON2, INTCON3 and INTCON4. INTCON1 contains the Interrupt Nesting Disable bit (NSTDIS), as well as the control and status flags for the processor trap sources. The INTCON2 register controls external interrupt request signal behavior and contains the Global Interrupt Enable bit (GIE). INTCON3 contains the status flags for the Auxiliary PLL and DO stack overflow status trap sources. The INTCON4 register contains the Generated Hard Trap Status bit (SGHT). 4.5.4.2 The IECx registers maintain all of the interrupt enable bits. These control bits are used to individually enable interrupts from the peripherals or external signals. 4.5.4.4 Software IFSx The IFSx registers maintain all of the interrupt request flags. Each source of interrupt has a status bit, which is set by the respective peripherals or external signal and is cleared via software. DS70005319B-page 322 IPCx The IPCx registers are used to set the Interrupt Priority Level (IPL) for each source of interrupt. Each user interrupt source can be assigned to one of seven priority levels. 4.5.5 INTTREG The INTTREG register contains the associated interrupt vector number and the new CPU Interrupt Priority Level, which are latched into the Vector Number (VECNUM<7:0>) and Interrupt Level bits (ILR<3:0>) fields in the INTTREG register. The new Interrupt Priority Level is the priority of the pending interrupt. The interrupt sources are assigned to the IFSx, IECx and IPCx registers in the same sequence as they are listed in Table 4-20. For example, INT0 (External Interrupt 0) is shown as having Vector Number 8 and a natural order priority of 0. Thus, the INT0IF bit is found in IFS0<0>, the INT0IE bit in IEC0<0> and the INT0IP<2:0> bits in the first position of IPC0 (IPC0<2:0>). 4.5.6 INTCON1 through INTCON4 IECx STATUS/CONTROL REGISTERS Although these registers are not specifically part of the interrupt control hardware, two of the CPU Control registers contain bits that control interrupt functionality. For more information on these registers, refer to "dsPIC33E Enhanced CPU" (DS70005158) in the "dsPIC33/PIC24 Family Reference Manual". * The CPU STATUS Register, SR, contains the IPL<2:0> bits (SR<7:5>). These bits indicate the current CPU Interrupt Priority Level. The user software can change the current CPU Interrupt Priority Level by writing to the IPLx bits. * The CORCON register contains the IPL3 bit which, together with IPL<2:0>, also indicates the current CPU priority level. IPL3 is a read-only bit so that trap events cannot be masked by the user software. All Interrupt registers are described in Register 4-18 through Register 4-22 on the following pages. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 4.5.7 SLAVE INTERRUPT CONTROL/STATUS REGISTERS REGISTER 4-16: SR: CPU STATUS REGISTER(1) R/W-0 R/W-0 R/W-0 R/W-0 R/C-0 R/C-0 R-0 R/W-0 OA OB SA SB OAB SAB DA DC bit 15 bit 8 R/W-0(3) IPL2 R/W-0(3) (2) IPL1 (2) R/W-0(3) R-0 R/W-0 R/W-0 R/W-0 R/W-0 IPL0(2) RA N OV Z C bit 7 bit 0 Legend: C = Clearable bit R = Readable bit W = Writable bit U = Unimplemented bit, read as `0' -n = Value at POR `1'= Bit is set `0' = Bit is cleared x = Bit is unknown IPL<2:0>: CPU Interrupt Priority Level Status bits(2,3) 111 = CPU Interrupt Priority Level is 7 (15); user interrupts are disabled 110 = CPU Interrupt Priority Level is 6 (14) 101 = CPU Interrupt Priority Level is 5 (13) 100 = CPU Interrupt Priority Level is 4 (12) 011 = CPU Interrupt Priority Level is 3 (11) 010 = CPU Interrupt Priority Level is 2 (10) 001 = CPU Interrupt Priority Level is 1 (9) 000 = CPU Interrupt Priority Level is 0 (8) bit 7-5 Note 1: 2: 3: For complete register details, see Register 4-1.

DS70005319B-page 329 dsPIC33CH128MP508 FAMILY 4.6 Slave I/O Ports Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "I/O Ports with Edge Detect" (DS70005322) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: The I/O ports are shared by the Master core and Slave core. All input goes to both the Master and Slave. The I/O ownership is defined by the Configuration bits. 3: The TMS pin function may be active multiple times during ICSPTM device erase, programming and debugging. When the TMS function is active, the integrated pull-up resistor will pull the pin to VDD. Proper care should be taken if there are sensitive circuits connected on the TMS pin during programming/erase and debugging. Many of the device pins are shared among the peripherals and the Parallel I/O ports. All I/O input ports feature Schmitt Trigger inputs for improved noise immunity. The Master and the Slave have the same number of I/O ports and are shared. The Master PORT registers are located in the Master SFR and the Slave PORT registers are located in the Slave SFR, respectively. All of the input goes to both Master and Slave. For example, a high in RA0 can be read as high on both Master and Slave as long as the TRISA0 bit is maintained as an input of both Master and Slave. The ownership of the output functionality is assigned by the Configuration registers, FCFGPRA0 to FCFGPRE0. Setting the bits in the FCFGPRA0 to FCFGPRE0 registers assigns ownership to the Master or Slave pin. DS70005319B-page 330 4.6.1 PARALLEL I/O (PIO) PORTS Generally, a Parallel I/O port that shares a pin with a peripheral is subservient to the peripheral. The peripheral's output buffer data and control signals are provided to a pair of multiplexers. The multiplexers select whether the peripheral or the associated port has ownership of the output data and control signals of the I/O pin. The logic also prevents "loop through", in which a port's digital output can drive the input of a peripheral that shares the same pin. Figure 4-17 illustrates how ports are shared with other peripherals and the associated I/O pin to which they are connected. When a peripheral is enabled and the peripheral is actively driving an associated pin, the use of the pin as a general purpose output pin is disabled. The I/O pin can be read, but the output driver for the parallel port bit is disabled. If a peripheral is enabled, but the peripheral is not actively driving a pin, that pin can be driven by a port. All port pins have twelve registers directly associated with their operation as digital I/Os. The Data Direction register (TRISx) determines whether the pin is an input or an output. If the data direction bit is a `1', then the pin is an input. All port pins are defined as inputs after a Reset. Reads from the latch (LATx), read the latch. Writes to the latch, write the latch. Reads from the port (PORTx), read the port pins, while writes to the port pins, write the latch. Any bit and its associated data and control registers that are not valid for a particular device are disabled. This means the corresponding LATx and TRISx registers, and the port pin are read as zeros. When a pin is shared with another peripheral or function that is defined as an input only, it is nevertheless regarded as a dedicated port because there is no other competing source of outputs. Table 4-24 shows the pin availability. Table 4-25 shows the 5V input tolerant pins across this device. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY TABLE 4-24: PIN AND ANSELx AVAILABILITY Device Rx15 Rx14 Rx13 Rx12 Rx11 Rx10 Rx9 Rx8 Rx7 Rx6 Rx5 Rx4 Rx3 Rx2 Rx1 Rx0 PORTA dsPIC33XXXMP508/208 -- -- -- -- -- -- -- -- -- -- -- X X X X X dsPIC33XXXMP506/206 -- -- -- -- -- -- -- -- -- -- -- X X X X X dsPIC33XXXMP505/205 -- -- -- -- -- -- -- -- -- -- -- X X X X X dsPIC33XXXMP503/203 -- -- -- -- -- -- -- -- -- -- -- X X X X X dsPIC33XXXMP502/202 -- -- -- -- -- -- -- -- -- -- -- X X X X X ANSELA -- -- -- -- -- -- -- -- -- -- -- X X X X -- PORTB dsPIC33XXXMP508/208 X X X X X X X X X X X X X X X X dsPIC33XXXMP506/206 X X X X X X X X X X X X X X X X dsPIC33XXXMP505/205 X X X X X X X X X X X X X X X X dsPIC33XXXMP503/203 X X X X X X X X X X X X X X X X dsPIC33XXXMP502/202 X X X X X X X X X X X X X X X X ANSELB -- -- -- -- -- -- -- X X -- -- X X X X X PORTC dsPIC33XXXMP508/208 X X X X X X X X X X X X X X X X dsPIC33XXXMP506/206 X X X X X X X X X X X X X X X X dsPIC33XXXMP505/205 -- -- X X X X X X X X X X X X X X dsPIC33XXXMP503/203 -- -- -- -- -- -- -- -- -- -- X X X X X X dsPIC33XXXMP502/202 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- ANSELC -- -- -- -- -- -- -- -- X X -- -- X X X X PORTD dsPIC33XXXMP508/208 X X X X X X X X X X X X X X X X dsPIC33XXXMP506/206 X X X X X X X X X X X X X X X X dsPIC33XXXMP505/205 -- -- X -- -- X -- X -- -- -- -- -- -- X -- dsPIC33XXXMP503/203 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- dsPIC33XXXMP502/202 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- ANSELD -- X X X X X -- -- -- -- -- -- -- -- -- -- PORTE dsPIC33XXXMP508/208 X X X X X X X X X X X X X X X X dsPIC33XXXMP506/206 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- dsPIC33XXXMP505/205 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- dsPIC33XXXMP503/203 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- dsPIC33XXXMP502/202 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- ANSELE -- -- -- -- -- -- -- -- -- X -- -- -- -- -- -- -- RA4 TABLE 4-25: PORTA PORTB -- 5V INPUT TOLERANT PORTS -- -- -- -- -- -- -- -- -- RA3 RA2 RA1 RA0 RB15 RB14 RB13 RB12 RB11 RB10 RB9 RB8 RB7 RB6 RB5 RB4 RB3 RB2 RB1 RB0 PORTC RC15 RC14 RC13 RC12 RC11 RC10 RC9 RC8 RC7 RC6 RC5 RC4 RC3 RC2 RC1 RC0 PORTD RD15 RD14 RD13 RD12 RD11 RD10 RD9 RD8 RD7 RD6 RD5 RD4 RD3 RD2 RD1 RD0 PORTE RE9 RE8 RE7 RE6 RE5 RE4 RE3 RE2 RE1 RE0 Legend: RE15 RE14 RE13 RE12 RE11 RE10 Shaded pins are up to 5.5 VDC input tolerant. 2017-2018 Microchip Technology Inc.

This is controlled by the Open-Drain Control x register, ODCx, associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain output. The open-drain feature allows the generation of outputs, other than VDD, by using external pull-up resistors. The maximum open-drain voltage allowed on any pin is the same as the maximum VIH specification for that particular pin. If the TRISx bit is cleared (output) while the ANSELx bit is set, the digital output level (VOH or VOL) is converted by an analog peripheral, such as the ADC module or comparator module. When the PORTx register is read, all pins configured as analog input channels are read as cleared (a low level). Pins configured as digital inputs do not convert an analog input. Analog levels on any pin, defined as a digital input (including the ANx pins), can cause the input buffer to consume current that exceeds the device specifications. 4.6.2.1 I/O Port Write/Read Timing See the "Pin Diagrams" section for the available 5V tolerant pins and Table 24-18 for the maximum VIH specification for each pin. One instruction cycle is required between a port direction change or port write operation and a read operation of the same port. Typically, this instruction would be a NOP, as shown in Example 4-3. 4.6.2 The following registers are in the PORT module: CONFIGURING ANALOG AND DIGITAL PORT PINS The ANSELx register controls the operation of the analog port pins. The port pins that are to function as analog inputs or outputs must have their corresponding ANSELx and TRISx bits set. In order to use port pins for I/O functionality with digital modules, such as timers, UARTs, etc., the corresponding ANSELx bit must be cleared. The ANSELx register has a default value of 0xFFFF; therefore, all pins that share analog functions are analog (not digital) by default.

This feature can detect input Change-ofStates, even in Sleep mode, when the clocks are disabled. Every I/O port pin can be selected (enabled) for generating an interrupt request on a Change-ofState. Five control registers are associated with the Change Notification (CN) functionality of each I/O port. To enable the Change Notification feature for the port, the ON bit (CNCONx<15>) must be set. The CNEN0x and CNEN1x registers contain the CN interrupt enable control bits for each of the input pins. The setting of these bits enables a CN interrupt for the corresponding pins. Also, these bits, in combination with the CNSTYLE bit (CNCONx<11>), define a type of transition when the interrupt is generated. Possible CN event options are listed in Table 4-26. The CNSTATx register indicates whether a change occurred on the corresponding pin since the last read of the PORTx bit. In addition to the CNSTATx register, the CNFx register is implemented for each port. This register contains flags for Change Notification events. These flags are set if the valid transition edge, selected in the CNEN0x and CNEN1x registers, is detected. CNFx stores the occurrence of the event. CNFx bits must be cleared in software to get the next Change Notification interrupt. The CN interrupt is generated only for the I/Os configured as inputs (corresponding TRISx bits must be set). 2017-2018 Microchip Technology Inc.

The challenge is even greater on low pin count devices. In an application where more than one peripheral needs to be assigned to a single pin, inconvenient work arounds in application code, or a complete redesign, may be the only option. Peripheral Pin Select configuration provides an alternative to these choices by enabling peripheral set selection and placement on a wide range of I/O pins. By increasing the pinout options available on a particular device, users can better tailor the device to their entire application, rather than trimming the application to fit the device. The Peripheral Pin Select configuration feature operates over a fixed subset of digital I/O pins. Users may independently map the input and/or output of most digital peripherals to any one of these I/O pins. Hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping once it has been established. 4.6.5.1 Available Pins The number of available pins is dependent on the particular device and its pin count. Pins that support the Peripheral Pin Select feature include the label, "S1RPn", in their full pin designation, where "n" is the remappable pin number. "S1RP" is used to designate pins that support both remappable input and output functions. 4.6.5.2 Available Peripherals In comparison, some digital only peripheral modules are never included in the Peripheral Pin Select feature. This is because the peripheral's function requires special I/O circuitry on a specific port and cannot be easily connected to multiple pins. One example includes I2C modules. A similar requirement excludes all modules with analog inputs, such as the ADC Converter. A key difference between remappable and nonremappable peripherals is that remappable peripherals are not associated with a default I/O pin. The peripheral must always be assigned to a specific I/O pin before it can be used. In contrast, non-remappable peripherals are always available on a default pin, assuming that the peripheral is active and not conflicting with another peripheral. When a remappable peripheral is active on a given I/O pin, it takes priority over all other digital I/Os and digital communication peripherals associated with the pin. Priority is given regardless of the type of peripheral that is mapped. Remappable peripherals never take priority over any analog functions associated with the pin. 4.6.5.3 Controlling Peripheral Pin Select Peripheral Pin Select features are controlled through two sets of SFRs: one to map peripheral inputs and one to map outputs. Because they are separately controlled, a particular peripheral's input and output (if the peripheral has both) can be placed on any selectable function pin without constraint. The association of a peripheral to a peripheralselectable pin is handled in two different ways, depending on whether an input or output is being mapped. The peripherals managed by the Peripheral Pin Select are all digital only peripherals. These include general serial communications (UART and SPI), general purpose timer clock inputs, timer-related peripherals (input capture and output compare) and interrupt-on-change inputs. DS70005319B-page 342 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 4.6.5.4 Input Mapping The inputs of the Peripheral Pin Select options are mapped on the basis of the peripheral. That is, a control register associated with a peripheral dictates the pin it will be mapped to. The RPINRx registers are used to configure peripheral input mapping (see Register 4-36 through Register 4-59). Each register contains sets of 8-bit fields, with each set associated with one of the remappable peripherals. Programming a given peripheral's bit field with an appropriate 8-bit index value maps the S1RPn pin with the corresponding value, or internal signal, to that peripheral. See Table 4-27 for a list of available inputs. FIGURE 4-18: REMAPPABLE INPUT FOR U1RX U1RXR<7:0> 0 VSS 1 Master CMP1 2 U1RX Input to Peripheral Slave CMP1 For example, Figure 4-18 illustrates remappable pin selection for the U1RX input. n S1RP181 Note: 2017-2018 Microchip Technology Inc. For input only, Peripheral Pin Select functionality does not have priority over TRISx settings. Therefore, when configuring an S1RPn pin for input, the corresponding bit in the TRISx register must also be configured for input (set to `1').

DS70005319B-page 345 dsPIC33CH128MP508 FAMILY 4.6.5.5 Virtual Connections The dsPIC33CH128MP508S1 family devices support six virtual S1RPn pins (S1RP170-S1RP175), which are identical in functionality to all other S1RPn pins, with the exception of pinouts. These six pins are internal to the devices and are not connected to a physical device pin. These pins provide a simple way for inter-peripheral connection without utilizing a physical pin. For example, the output of the analog comparator can be connected to S1RP170 and the PWM control input can be configured for S1RP170 as well. This configuration allows the analog comparator to trigger PWM Faults without the use of an actual physical pin on the device. 4.6.5.6 Slave PPS Inputs to Master Core PPS The dsPIC33CH128MP508S1 Slave core subsystem PPS has connections to the Master core subsystem virtual PPS (S1RPV5-S1RPV0) output blocks. These inputs are mapped as S1RP175, S1RP174, S1RP173, S1RP172, S1RP171 and S1RP170. The S1RPn inputs, S1RP1-S1RP13, are connected to internal signals from both the Master and Slave core subsystems. Additionally, the Master core virtual PPS output blocks (RPV5-RPV0) are connected to the Slave core PPS circuitry.

In this case, a control register associated with a particular pin dictates the peripheral output to be mapped. The RPORx registers are used to control output mapping. Each register contains sets of 6-bit fields, with each set associated with one S1RPn pin (see Register 4-60 through Register 4-82). The value of the bit field corresponds to one of the peripherals and that peripheral's output is mapped to the pin (see Table 4-31 and Figure 4-19). Mapping Limitations The control schema of the peripheral select pins is not limited to a small range of fixed peripheral configurations. There are no mutual or hardware-enforced lockouts between any of the peripheral mapping SFRs. Literally any combination of peripheral mappings, across any or all of the S1RPn pins, is possible. This includes both many-to-one and one-to-many mappings of peripheral inputs, and outputs to pins. While such mappings may be technically possible from a configuration point of view, they may not be supportable from an electrical point of view. A null output is associated with the PPS Output register Reset value of `0'. This is done to ensure that remappable outputs remain disconnected from all output pins by default.

I/O HELPFUL TIPS In some cases, certain pins, as defined in Table 24-18 under "Injection Current", have internal protection diodes to VDD and VSS. The term, "Injection Current", is also referred to as "Clamp Current". On designated pins, with sufficient external current-limiting precautions by the user, I/O pin input voltages are allowed to be greater or lesser than the data sheet absolute maximum ratings, with respect to the VSS and VDD supplies. Note that when the user application forward biases either of the high or low-side internal input clamp diodes, that the resulting current being injected into the device, that is clamped internally by the VDD and VSS power rails, may affect the ADC accuracy by four to six counts. I/O pins that are shared with any analog input pin (i.e., ANx) are always analog pins, by default, after any Reset. Consequently, configuring a pin as an analog input pin automatically disables the digital input pin buffer and any attempt to read the digital input level by reading PORTx or LATx will always return a `0', regardless of the digital logic level on the pin. To use a pin as a digital I/O pin on a shared ANx pin, the user application needs to configure the Analog Select for PORTx registers, in the I/O ports module (i.e., ANSELx), by setting the appropriate bit that corresponds to that I/O port pin to a `0'. Note: Although it is not possible to use a digital input pin when its analog function is enabled, it is possible to use the digital I/O output function, TRISx = 0x0, while the analog function is also enabled. However, this is not recommended, particularly if the analog input is connected to an external analog voltage source, which would create signal contention between the analog signal and the output pin driver. 2017-2018 Microchip Technology Inc. 3. 4. 5. Most I/O pins have multiple functions. Referring to the device pin diagrams in this data sheet, the priorities of the functions allocated to any pins are indicated by reading the pin name, from left-to-right. The left most function name takes precedence over any function to its right in the naming convention. For example: AN16/T2CK/T7CK/RC1; this indicates that AN16 is the highest priority in this example and will supersede all other functions to its right in the list. Those other functions to its right, even if enabled, would not work as long as any other function to its left was enabled. This rule applies to all of the functions listed for a given pin. Each pin has an internal weak pull-up resistor and pull-down resistor that can be configured using the CNPUx and CNPDx registers, respectively. These resistors eliminate the need for external resistors in certain applications. The internal pull-up is up to ~(VDD - 0.8), not VDD. This value is still above the minimum VIH of CMOS and TTL devices. When driving LEDs directly, the I/O pin can source or sink more current than what is specified in the VOH/IOH and VOL/IOL DC characteristics specification. The respective IOH and IOL current rating only applies to maintaining the corresponding output at or above the VOH, and at or below the VOL levels. However, for LEDs, unlike digital inputs of an externally connected device, they are not governed by the same minimum VIH/VIL levels. An I/O pin output can safely sink or source any current less than that listed in the Absolute Maximum Ratings in Section 24.0 "Electrical Characteristics" of this data sheet. For example: VOH = 2.4v @ IOH = -8 mA and VDD = 3.3V The maximum output current sourced by any 8 mA I/O pin = 12 mA. LED source current < 12 mA is technically permitted.

The Peripheral Pin Select (PPS) pin mapping rules are as follows: a) Only one "output" function can be active on a given pin at any time, regardless if it is a dedicated or remappable function (one pin, one output). b) It is possible to assign a "remappable output" function to multiple pins and externally short or tie them together for increased current drive. c) If any "dedicated output" function is enabled on a pin, it will take precedence over any remappable "output" function. d) If any "dedicated digital" (input or output) function is enabled on a pin, any number of "input" remappable functions can be mapped to the same pin. e) If any "dedicated analog" function(s) are enabled on a given pin, "digital input(s)" of any kind will all be disabled, although a single "digital output", at the user's cautionary discretion, can be enabled and active as long as there is no signal contention with an external analog input signal. For example, it is possible for the ADC to convert the digital output logic level, or to toggle a digital output on a comparator or ADC input, provided there is no external analog input, such as for a Built-In Self-Test. f) Any number of "input" remappable functions can be mapped to the same pin(s) at the same time, including to any pin with a single output from either a dedicated or remappable "output". g) The TRISx registers control only the digital I/O output buffer. Any other dedicated or remappable active "output" will automatically override the TRISx setting. The TRISx register does not control the digital logic "input" buffer. Remappable digital "inputs" do not automatically override TRISx settings, which means that the TRISx bit must be set to input for pins with only remappable input function(s) assigned. h) All analog pins are enabled by default after any Reset and the corresponding digital input buffer on the pin has been disabled. Only the Analog Select for PORTx (ANSELx) registers control the digital input buffer, not the TRISx register. The user must disable the analog function on a pin using the Analog Select for PORTx registers in order to use any "digital input(s)" on a corresponding pin, no exceptions.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "12-Bit High-Speed, Multiple SARs A/D Converter (ADC)" (DS70005213) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: This section describes the Slave ADC. dsPIC33CH128MP508S1 devices have a high-speed, 12-bit Analog-to-Digital Converter (ADC) that features a low conversion latency, high resolution and oversampling capabilities to improve performance in AC/DC, DC/DC power converters. The Slave implements the ADC with three SAR cores, two dedicated and one shared. 4.7.1 SLAVE ADC FEATURES OVERVIEW The High-Speed, 12-Bit Multiple SARs Analog-to-Digital Converter (ADC) includes the following features: * Three ADC Cores: Two Dedicated Cores and One Shared (common) Core * User-Configurable Resolution of up to 12 Bits for each Core * Up to 3.5 Msps Conversion Rate per Channel at 12-Bit Resolution * Low-Latency Conversion * Up to 20 Analog Input Channels, with a Separate 16-Bit Conversion Result Register for each Input * Conversion Result can be Formatted as Unsigned or Signed Data, on a per Channel Basis, for All Channels * Simultaneous Sampling of up to Three Analog Inputs * Channel Scan Capability * Multiple Conversion Trigger Options for each Core, including: - PWM triggers from Master and Slave CPU cores - SCCP modules triggers - CLC modules triggers - External pin trigger event (ADTRG31) - Software trigger * Four Integrated Digital Comparators with Dedicated Interrupts: - Multiple comparison options - Assignable to specific analog inputs * Four Oversampling Filters with Dedicated Interrupts: - Provide increased resolution - Assignable to a specific analog input * CVD Hardware for Capacitive Touch and Capacitance Measurement Applications The module consists of three independent SAR ADC cores. Simplified block diagrams of the Multiple SARs 12-Bit ADC are shown in Figure 4-20 and Figure 4-21. The analog inputs (channels) are connected through multiplexers and switches to the Sample-and-Hold (S&H) circuit of each ADC core. The core uses the channel information (the output format, the Measurement mode and the input number) to process the analog sample. When conversion is complete, the result is stored in the result buffer for the specific analog input, and passed to the digital filter and digital comparator if they were configured to use data from this particular channel. The ADC module can sample up to three inputs at a time (two inputs from the dedicated SAR cores and one from the shared SAR core). If multiple ADC inputs request conversion on the shared core, the module will convert them in a sequential manner, starting with the lowest order input. The ADC provides each analog input the ability to specify its own trigger source.

DS70005319B-page 411 dsPIC33CH128MP508 FAMILY 4.8 Programmable Gain Amplifier (PGA) Slave Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Programmable Gain Amplifier (PGA)" (DS70005146) in the "dsPIC33/ PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The dsPIC33CH128MP508S1 family devices have three Programmable Gain Amplifiers (PGA1, PGA2, PGA3). The PGA is an op amp-based, non-inverting amplifier with user-programmable gains. The output of the PGA can be connected to a number of dedicated Sample-and-Hold inputs of the Analog-to-Digital Converter and/or to the high-speed analog comparator module. The PGA has four selectable gains and may FIGURE 4-23: be used as a ground referenced amplifier (singleended) or used with an independent ground reference point. Key features of the PGA module include: * Single-Ended or Independent Ground Reference * Selectable Gains: 4x, 8x, 16x and 32x (and 6x,12x, 24x and 48x with the 1.5 gain) * High-Gain Bandwidth * Rail-to-Rail Output Voltage * Wide Input Voltage Range Table 4-38 shows an overview of the PGA module.

To provide an independent ground reference, S1PGAxN2 is available as the negative input source to the PGAx module. The Programmable Gain Amplifiers are used to amplify small voltages (i.e., voltages across burden/shunt resistors) to improve the Signal-to-Noise Ratio (SNR) of the measured signal. The PGAx output voltage can be read by any of the four dedicated Sample-and-Hold circuits on the ADC module. The output voltage can also be fed to the comparator module for overcurrent/ voltage protection. Figure 4-24 shows a functional block diagram of the PGAx module. Refer to Section 3.9 "High-Speed, 12-Bit Analog-to-Digital Converter (Master ADC)" for more interconnection details. Note 1: Not all PGA positive/negative inputs are available on all devices. Refer to the specific device pinout for available input source pins. The output voltage of the PGAx module can be connected to the DACOUT pin by setting the PGAOEN bit in the PGAxCON register. When the PGAOEN bit is enabled, the output voltage of PGA1 is connected to DACOUT. There is only one DACOUT pin. The gain of the PGAx module is selectable via the GAIN<2:0> bits in the PGAxCON register. There are four gains, ranging from 4x to 48x (with a 1.5 gain multiplier). The SELPI<2:0> and SELNI<2:0> bits in the PGAxCON register select one of the positive/negative inputs to the PGAx module. For single-ended applica- FIGURE 4-24: If all three of the DACx output voltages and PGAx output voltages are connected to the DACOUT pin, the resulting output voltage would be a combination of signals. There is no assigned priority between the PGAx module and the DACx module.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Master Slave Interface (MSI) Module" (DS70005278) in the "dsPIC33/ PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The Master Slave Interface (MSI) module is a bridge between the Master and a Slave processor system, each of which operates within independent clock domains. The Master and Slave have their own registers to communicate between the MSI modules; the Master MSI registers are located in the Master SFR space and the Slave MSI registers are in the Slave SFR space. The Master Slave Interface (MSI) includes these characteristics: * 16 Unidirectional Data Mailbox Registers: - Direction of each Mailbox register is fuse-selectable - Byte and word-addressable * Eight Mailbox Data Flow Control Protocol Blocks: - Individual fuse enables - Write port active; read port passive (i.e., no read data request required) - Automatic, interrupt driven (or polled), data flow control mechanism across MSI clock boundary - Fuse assignable to any of the Mailbox registers, supports any length data buffers (up to the number of available Mailbox registers) - DMA transfer compatible * Master to Slave and Slave to Master Interrupt Request with Acknowledge Data Flow Control * Optional (parameterized) 2-Channel FIFO Memory Structure * Parameterized Depth (between 16 and 32 words): - One read and one write channel - Circular operation with empty and full status, and interrupts - Overflow/underflow detection with interrupts to Master core and Slave core - Interrupt-based, software polled or DMA transfer compatible 2017-2018 Microchip Technology Inc. * Master and Slave Processor Cross-Boundary Control and Status: - Readable operating mode status for both processors - Slave enable from Master (subject to satisfying a hardware write interlock sequencer) - Master interrupt when Slave is reset during code execution - Slave interrupt when Master is reset during code execution * Optional (fuse) Decoupling of Master and Slave Resets; POR/BOR/MCLR always Resets Master and Slave; Influence of Remaining Run-Time Resets on the Slave Enable is Fuse-Programmable 5.1 Master MSI Control Registers The following registers are associated with the Master MSI module and are located in the Master SFR space. * * * * * * * * Register 5-1: MSI1CON Register 5-2: MSI1STAT Register 5-3: MSI1KEY Register 5-4: MSI1MBXS Register 5-5: MSI1MBXnD Register 5-6: MSI1FIFOCS Register 5-7: MRSWFDATA Register 5-8: MWSRFDATA DS70005319B-page 417 dsPIC33CH128MP508 FAMILY REGISTER 5-1: MSI1CON: MSI1 MASTER CONTROL REGISTER R/W-0 U-0 U-0 U-0 R/W-0 R/W-0 R/W-0 R/W-0 SLVEN -- -- -- RFITSEL1 RFITSEL0 MTSIRQ STMIACK bit 15 bit 8 R/W-0 r-0 r-0 r-0 r-0 r-0 r-0 r-0 SRSTIE -- -- -- -- -- -- -- bit 7 bit 0 Legend: r = Reserved bit R = Readable bit W = Writable bit U = Unimplemented bit, read as `0' -n = Value at POR `1' = Bit is set `0' = Bit is cleared x = Bit is unknown bit 15 SLVEN: Slave Enable bit This bit enables the Slave processor subsystem.

When the SLVEN bit lock is enabled (i.e., the bits are locked and cannot be modified), the instruction sequence shown in Example 5-1 must be executed to open the lock. The unlock sequence is a prerequisite to both setting and clearing the target control bit. Note: The Slave is disabled when SLVEN (MSI1CON<15>) = 0. In this state: * The Slave is held in the Reset state * The Master has access to the Slave PRAM (to load it out of a device Reset) * The Slave Reset status bit, SLVRST (MSI1STAT<15>) = 1 The Slave is enabled when SLVEN (MSI1CON<15>) = 1. In this state: * The Slave Reset is released and it will start to execute code in whatever mode it is configured to operate in * The Master processor will no longer have access to the Slave PRAM * The Slave Reset status bit, SLVRST (MSI1STAT<15>) = 0 Note: The SLVRST (MSI1STAT<15>) status bit indicates when the Slave is in Reset. The associated interrupt only occurs when the Slave enters the Reset state after having previously not been in Reset. That is, no interrupt can be generated until the Slave is first enabled. The SLVEN bit may only be modified after satisfying the hardware write interlock. The SLVEN bit is protected from unexpected writes through a software unlocking sequence that is based on the MSI1KEY register. Given the critical nature of the MSI control interface, the MSI macro unlock mechanism is independent from that of the Flash controller for added robustness. Completing a predefined data write sequence to the MSI1KEY register will open a window. The SLVEN bit should be written on the first instruction that follows the unlock sequence. No other bits within the MSI1CON register are affected by the interlock. The MSI1KEY register is not a physical register. A read of the MSI1KEY register will read all `0's. 2017-2018 Microchip Technology Inc. It is recommended to enable SRSTIE (MSI1CON<7>) = 1 prior to enabling the SLVEN bit. This will make the design robust and will update the Master with the Reset state of the Slave.

The Resets are effectively coupled by directing the selected Reset source to the SLVEN bit Reset. In all operating modes, the user may also choose whether the SLVEN bit is reset or not in the event of a Slave Run-Time Reset by using the Slave Reset Enable (S1SSRE) fuse. A user may choose to reset SLVEN in the event of a Slave Reset because that event could be an indicator of a problem with Slave execution. The Slave would be placed in Reset and the Master alerted (via the Slave Reset event interrupt, need to make SRSTIE (MSI1CON<7> = 1) to attempt to rectify the problem. The Master must re-enable the Slave by setting the SLVEN bit again. Alternatively, the user may choose to not halt the Slave in the event of a Slave Reset, and just allow it to restart execution after a Reset and continue operation as soon as possible. The Slave Reset event interrupt would still occur, but could be ignored by the Master.

POR/BOR/MCLR(1) Slave Resets(2) * Slave is reset and disabled in the event of any Slave Run-Time Reset or Master Reset. Master must re-enable Slave. This represents the default state (S1MSRE and S1SSRE are unprogrammed). Master Resets include any Master Reset, such as POR/BOR/MCLR Resets. Slave Resets include any Slave Reset, plus POR/BOR/MCLR Resets (in Application mode). INTER-PROCESSOR INTERRUPT REQUEST AND ACKNOWLEDGE The Master and Slave processors may interrupt each other directly. The Master may issue an interrupt request to the Slave by asserting the MTSIRQ (MSI1CON<9>) control bit. Similarly, the Slave may issue an interrupt request to the Master by asserting the STMIRQ (MSI1STAT<9>) control bit. The interrupts are Acknowledged through the use of the Interrupt Acknowledge bits, MTSIACK (MSI1STAT<8>) for the Master to Slave interrupt request and STMIACK (MSI1CON<8>) for the Slave to Master interrupt request. DS70005319B-page 430 5.4.2 READ ADDRESS POINTERS FOR FIFOs The MSI macro may also include a set of two FIFOs, one for data reads from the Slave and the other for data writes to the Slave. The Read Address Pointers for the Read and Write FIFOs are held in the RDPTR<6:0> bits (MSI1CON<6:0>) and WRPTR<6:0 bits (MSI1STAT<6:0>), respectively. These bits are accessible only from within Debug mode. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 6.0 OSCILLATOR WITH HIGH-FREQUENCY PLL * Master and Slave Independent On-Chip Phase-Locked Loop (PLL) to Boost Internal Operating Frequency on Select Internal and External Oscillator Sources * Master and Slave Independent Auxiliary PLL (APLL) Clock Generator to Boost Operating Frequency for Peripherals * Master and Slave Independent Doze mode for System Power Savings * Master and Slave Independent Scalable Reference Clock Output (REFCLKO) * On-the-Fly Clock Switching between Various Clock Sources * Fail-Safe Clock Monitoring (FSCM) that Detects Clock Failure and Permits Safe Application Recovery or Shutdown Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices.

There are two independent instantiations of PLL for the Master and Slave clock subsystems. Figure 6-4 illustrates a block diagram of the Master/Slave core PLL module. For PLL operation, the following requirements must be met at all times without exception: * The PLL Input Frequency (FPLLI) must be in the range of 8 MHz to 64 MHz * The PFD Input Frequency (FPFD) must be in the range of 8 MHz to (FVCO/16) MHz The VCO Output Frequency (FVCO) must be in the range of 400 MHz to 1600 MHz FIGURE 6-4: MASTER/SLAVE CORE PLL AND VCO DETAIL COSC<2:0> FRCCLK(1) POSCCLK(1) S1 S3 DIV 1-8 POST1DIV<2:0> PLL Ready (LOCK) PLLPRE<3:0> Lock Detect PFD VCO POST2DIV<2:0> DIV 1-7 DIV 1-7 Feedback Divider 16-200 PLLFBDIV<7:0> FPLLO(2,4) FVCO VCO Divider FVCO FVCO/2(4) FVCO/3 FVCO/4(3) FVCODIV VCODIV<1:0> Note 1: 2: 3: 4: From Master and Slave core shared oscillator source.

Therefore, the user must start in either a nonPLL mode or clock switch to a non-PLL mode (e.g., internal FRC Oscillator) to make any necessary changes and then clock switch to the desired PLL mode. It is not permitted to directly clock switch from one PLL clock source to a different PLL clock source. The user would need to transition between PLL clock sources with a clock switch to a non-PLL clock source. 2017-2018 Microchip Technology Inc.

There are two independent instantiations of APLL for the Master and Slave clock subsystems. The APLL is used to generate various peripheral clock sources independent of the system clock. Figure 6-5 shows a block diagram of the Master/Slave core APLL module.

In this document, the instruction cycle clock is denoted by FCY. The timing diagram in Figure 6-6 illustrates the relationship between the system clock (FOSC), the instruction cycle clock (FCY) and the Program Counter (PC). While the Master and Slave subsystems share access to a single set of oscillator sources, all other clocking logic is implemented individually. The Master and Slave core can be configured independently to use any of the following clock configurations: * Primary Oscillator (POSC) on the OSCI and OSCO pins * Internal Fast RC Oscillator (FRC) with optional clock divider * Internal Low-Power RC Oscillator (LPRC) * Primary Oscillator with PLL (ECPLL, HSPLL, XTPLL) * Internal Fast RC Oscillator with PLL (FRCPLL) * Backup Internal Fast RC Oscillator (BFRC) FIGURE 6-6: The internal instruction cycle clock (FCY) can be output on the OSCO I/O pin if the Primary Oscillator mode (POSCMD<1:0>) is not configured as HS/XT.

DS70005319B-page 465 dsPIC33CH128MP508 FAMILY 6.6 Primary Oscillator (POSC) 6.8 Low-Power RC (LPRC) Oscillator The dsPIC33CH128MP508 family devices contain one instance of the Primary Oscillator (POSC), which is available to both the Master and Slave clock subsystems. The Primary Oscillator is available on the OSCI and OSCO pins of the dsPIC33CH devices. This connection enables an external crystal (or ceramic resonator) to provide the clock to the device. The Primary Oscillator provides three modes of operation: The dsPIC33CH128MP508 family devices contain one instance of the Low-Power RC (LPRC) Oscillator that is available to both the Master and Slave clock subsystems. The LPRC Oscillator provides a nominal clock frequency of 32 kHz and is the clock source for the Power-up Timer (PWRT), Watchdog Timer (WDT) and Fail-Safe Clock Monitor (FSCM) circuits in each core clock subsystem. * Medium Speed Oscillator (XT Mode): The XT mode is a Medium Gain, Medium Frequency mode used to work with crystal frequencies of 3.5 MHz to 10 MHz. * High-Speed Oscillator (HS Mode): The HS mode is a High-Gain, High-Frequency mode used to work with crystal frequencies of 10 MHz to 32 MHz. * External Clock Source Operation (EC Mode): If the on-chip oscillator is not used, the EC mode allows the internal oscillator to be bypassed. The device clocks are generated from an external source (0 MHz to up to 64 MHz) and input on the OSCI pin. The LPRC Oscillator is the clock source for the PWRT, WDT and FSCM in both the Master and Slave cores. The LPRC Oscillator is enabled at power-on. Note: 6.7 The Primary Oscillator (POSC) is shared between Master and Slave. The LPRC Oscillator remains enabled under these conditions: * The Master or Slave FSCM is enabled * The Master or Slave WDT is enabled * The LPRC Oscillator is selected as the system clock If none of these conditions is true, the LPRC Oscillator shuts off after the PWRT expires. The LPRC Oscillator is shut off in Sleep mode. Note: The LPRC is shared between Master and Slave. Internal Fast RC (FRC) Oscillator The dsPIC33CH128MP508 family devices contain one instance of the internal Fast RC (FRC) Oscillator, which is available to both the Master and Slave clock subsystems. The FRC Oscillator provides a nominal 8 MHz clock without requiring an external crystal or ceramic resonator, which results in system cost savings for applications that do not require a precise clock reference. The application software can tune the frequency of the oscillator using the FRC Oscillator Tuning bits (TUN<5:0>) in the FRC Oscillator Tuning register (OSCTUN<5:0>). Note: The FRC is shared between Master and Slave; the OSCTUN register is used to tune the FRC as a part of the Master oscillator configuration.

DS70005319B-page 470 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 7.0 POWER-SAVING FEATURES (MASTER AND SLAVE) Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Watchdog Timer and Power-Saving Modes" (DS70615) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The power saving section is only relevant for this device. The WDT has its own family reference manual section. 2: This chapter is applicable to both the Master core and the Slave core. There are registers associated with PMD that are listed separately for Master and Slave at the end of this section. Other features related to power saving that are discussed are applicable to both the Master and Slave core. 3: All associated register names are the same on the Master core and the Slave core. The Slave code will be developed in a separate project in MPLAB(R) X IDE with the device selection, dsPIC33CH128MP508S1, where S1 indicates the Slave device. The dsPIC33CH128MP508 family devices provide the ability to manage power consumption by selectively managing clocking to the CPU and the peripherals. In general, a lower clock frequency and a reduction in the number of peripherals being clocked constitutes lower consumed power. dsPIC33CH128MP508 family devices can manage power consumption in four ways: * * * * Clock Frequency Instruction-Based Sleep and Idle modes Software-Controlled Doze mode Selective Peripheral Control in Software Combinations of these methods can be used to selectively tailor an application's power consumption while still maintaining critical application features, such as timing-sensitive communications. 7.1 Clock Frequency and Clock Switching The dsPIC33CH128MP508 family devices allow a wide range of clock frequencies to be selected under application control. If the system clock configuration is not locked, users can choose low-power or high-precision oscillators by simply changing the NOSCx bits (OSCCON<10:8>). The process of changing a system clock during operation, as well as limitations to the process, are discussed in more detail in Section 6.0 "Oscillator with High-Frequency PLL". 7.2 Instruction-Based Power-Saving Modes The dsPIC33CH128MP508 family devices have two special power-saving modes that are entered through the execution of a special PWRSAV instruction. Sleep mode stops clock operation and halts all code execution. Idle mode halts the CPU and code execution, but allows peripheral modules to continue operation. The assembler syntax of the PWRSAV instruction is shown in Example 7-1. Note: SLEEP_MODE and IDLE_MODE are constants defined in the assembler include file for the selected device. Sleep and Idle modes can be exited as a result of an enabled interrupt, WDT time-out or a device Reset. When the device exits these modes, it is said to "wake-up". EXAMPLE 7-1: PWRSAV INSTRUCTION SYNTAX PWRSAV #SLEEP_MODE PWRSAV #IDLE_MODE ; Put the device into Sleep mode ; Put the device into Idle mode 2017-2018 Microchip Technology Inc. DS70005319B-page 471 dsPIC33CH128MP508 FAMILY 7.2.1 SLEEP MODE 7.2.2 IDLE MODE The following occurs in Sleep mode: The following occurs in Idle mode: * The system clock source is shut down. If an on-chip oscillator is used, it is turned off. * The device current consumption is reduced to a minimum, provided that no I/O pin is sourcing current. * The Fail-Safe Clock Monitor does not operate, since the system clock source is disabled. * The LPRC clock continues to run in Sleep mode if the WDT is enabled. * The WDT, if enabled, is automatically cleared prior to entering Sleep mode. * Some device features or peripherals can continue to operate. This includes items such as the Input Change Notification on the I/O ports or peripherals that use an External Clock input. * Any peripheral that requires the system clock source for its operation is disabled. * The CPU stops executing instructions. * The WDT is automatically cleared. * The system clock source remains active. By default, all peripheral modules continue to operate normally from the system clock source, but can also be selectively disabled (see Section 7.4 "Peripheral Module Disable"). * If the WDT or FSCM is enabled, the LPRC also remains active. The device wakes up from Sleep mode on any of the these events: * Any interrupt source that is individually enabled * Any form of device Reset * A WDT time-out On wake-up from Sleep mode, the processor restarts with the same clock source that was active when Sleep mode was entered. For optimal power savings, the internal regulator and the Flash regulator can be configured to go into standby when Sleep mode is entered by clearing the VREGS (RCON<8>) bit. DS70005319B-page 472 The device wakes from Idle mode on any of these events: * Any interrupt that is individually enabled * Any device Reset * A WDT time-out On wake-up from Idle mode, the clock is reapplied to the CPU and instruction execution will begin (2-4 clock cycles later), starting with the instruction following the PWRSAV instruction or the first instruction in the ISR. All peripherals also have the option to discontinue operation when Idle mode is entered to allow for increased power savings. This option is selectable in the control register of each peripheral; for example, the SIDL bit in the Timer1 Control register (T1CON<13>). 7.2.3 INTERRUPTS COINCIDENT WITH POWER SAVE INSTRUCTIONS Any interrupt that coincides with the execution of a PWRSAV instruction is held off until entry into Sleep or Idle mode has completed. The device then wakes up from Sleep or Idle mode. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 7.3 Doze Mode The preferred strategies for reducing power consumption are changing clock speed and invoking one of the power-saving modes. In some circumstances, this cannot be practical. For example, it may be necessary for an application to maintain uninterrupted synchronous communication, even while it is doing nothing else. Reducing system clock speed can introduce communication errors, while using a power-saving mode can stop communications completely. Note 1: If a PMD bit is set, the corresponding module is disabled after a delay of one instruction cycle. Similarly, if a PMD bit is cleared, the corresponding module is enabled after a delay of one instruction cycle (assuming the module control registers are already configured to enable module operation). 2: The PMD bits are different for the Master core and Slave core. The Master has its own PMD bits which can be disabled/ enabled independently of the Slave peripherals. The Slave has its own PMD bits which can be disabled/enabled independently of the Master peripherals. The register names are the same for the Master and the Slave, but the PMD registers have different addresses in the Master and Slave SFR. Doze mode is a simple and effective alternative method to reduce power consumption while the device is still executing code. In this mode, the system clock continues to operate from the same source and at the same speed. Peripheral modules continue to be clocked at the same speed, while the CPU clock speed is reduced. Synchronization between the two clock domains is maintained, allowing the peripherals to access the SFRs while the CPU executes code at a slower rate. Doze mode is enabled by setting the DOZEN bit (CLKDIV<11>). The ratio between peripheral and core clock speed is determined by the DOZE<2:0> bits (CLKDIV<14:12>). There are eight possible configurations, from 1:1 to 1:128, with 1:1 being the default setting. Programs can use Doze mode to selectively reduce power consumption in event-driven applications. This allows clock-sensitive functions, such as synchronous communications, to continue without interruption while the CPU Idles, waiting for something to invoke an interrupt routine. An automatic return to full-speed CPU operation on interrupts can be enabled by setting the ROI bit (CLKDIV<15>). By default, interrupt events have no effect on Doze mode operation. 7.4 Peripheral Module Disable The Peripheral Module Disable (PMD) registers provide a method to disable a peripheral module by stopping all clock sources supplied to that module. When a peripheral is disabled using the appropriate PMD control bit, the peripheral is in a minimum power consumption state. The control and status registers associated with the peripheral are also disabled, so writes to those registers do not have any effect and read values are invalid. A peripheral module is enabled only if both the associated bit in the PMD register is cleared and the peripheral is supported by the specific dsPIC(R) DSC variant. If the peripheral is present in the device, it is enabled in the PMD register by default. 2017-2018 Microchip Technology Inc. 7.5 Power-Saving Resources Many useful resources are provided on the main product page of the Microchip web site for the devices listed in this data sheet.

It is not intended to be a comprehensive reference source. For more information, refer to "Direct Memory Access Controller (DMA)" (DS39742) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: The DMA is identical for both Master core and Slave core. The x is common for both Master and Slave (where the x represents the number of the specific module being addressed). 3: All associated register names are the same on the Master core and the Slave core. The Slave code will be developed in a separate project in MPLAB(R) X IDE with the device selection, dsPIC33CH128MP508S1, where S1 indicates the Slave device. Table 8-1 shows an overview of the DMA module. TABLE 8-1: DMA MODULE OVERVIEW Number of DMA Modules Identical (Modules) Master Core 6 Yes Slave Core 2 Yes The Direct Memory Access (DMA) Controller is designed to service high data throughput peripherals operating on the SFR bus, allowing them to access data memory directly and alleviating the need for CPU-intensive management. By allowing these data-intensive peripherals to share their own data path, the main data bus is also deloaded, resulting in additional power savings. 2017-2018 Microchip Technology Inc. The DMA Controller functions both as a peripheral and a direct extension of the CPU. It is located on the microcontroller data bus, between the CPU and DMA-enabled peripherals, with direct access to SRAM. This partitions the SFR bus into two buses, allowing the DMA Controller access to the DMA-capable peripherals located on the new DMA SFR bus. The controller serves as a Master device on the DMA SFR bus, controlling data flow from DMA-capable peripherals. The controller also monitors CPU instruction processing directly, allowing it to be aware of when the CPU requires access to peripherals on the DMA bus and automatically relinquishing control to the CPU as needed. This increases the effective bandwidth for handling data without DMA operations, causing a processor Stall. This makes the controller essentially transparent to the user. The DMA Controller has these features: * A Total of Eight (Six Master, Two Slave), Independently Programmable Channels * Concurrent Operation with the CPU (no DMA caused Wait states) * DMA Bus Arbitration * Five Programmable Address modes * Four Programmable Transfer modes * Four Flexible Internal Data Transfer modes * Byte or Word Support for Data Transfer * 16-Bit Source and Destination Address Register for each Channel, Dynamically Updated and Reloadable * 16-Bit Transaction Count Register, Dynamically Updated and Reloadable * Upper and Lower Address Limit Registers * Counter Half-Full Level Interrupt * Software Triggered Transfer * Null Write mode for Symmetric Buffer Operations A simplified block diagram of the DMA Controller is shown if Figure 8-1.

Each of these parameters can be independently configured for any transaction. In addition, any or all of the DMA channels can independently perform a different transaction at the same time. Transactions are classified by these parameters: * * * * Source and destination (SFRs and data RAM) Data size (byte or word) Trigger source Transfer mode (One-Shot, Repeated or Continuous) * Addressing modes (Fixed Address or Address Blocks with or without Address Increment/Decrement) In addition, the DMA Controller provides channel priority arbitration for all channels. 8.1.1 SOURCE AND DESTINATION Using the DMA Controller, data may be moved between any two addresses in the Data Space. The SFR space (0000h to 0FFFh) or the data RAM space (Master is 1000h to 4FFFh and Slave is 1000 to 1FFFh) can serve as either the source or the destination. Data can be moved between these areas in either direction or between addresses in either area. The four different combinations are shown in Figure 8-2. If it is necessary to protect areas of data RAM, the DMA Controller allows the user to set upper and lower address boundaries for operations in the Data Space above the SFR space. The boundaries are set by the DMAH and DMAL Limit registers. If a DMA channel attempts an operation outside of the address boundaries, the transaction is terminated and an interrupt is generated. 8.1.2 DATA SIZE The DMA Controller can handle both 8-bit and 16-bit transactions. Size is user-selectable using the SIZE bit (DMACHn<1>). By default, each channel is configured for word-size transactions. When byte-size transactions are chosen, the LSB of the source and/or destination address determines if the data represents the upper or lower byte of the data RAM location. 8.1.3 TRIGGER SOURCE The DMA Controller can use 82 of the device's interrupt sources to initiate a transaction. The DMA trigger sources occur in reverse order from their natural interrupt priority and are shown in Table 8-2. 2017-2018 Microchip Technology Inc. Since the source and destination addresses for any transaction can be programmed independently of the trigger source, the DMA Controller can use any trigger to perform an operation on any peripheral. This also allows DMA channels to be cascaded to perform more complex transfer operations. 8.1.4 TRANSFER MODE The DMA Controller supports four types of data transfers, based on the volume of data to be moved for each trigger. * One-Shot: A single transaction occurs for each trigger. * Continuous: A series of back-to-back transactions occur for each trigger; the number of transactions is determined by the DMACNTn transaction counter. * Repeated One-Shot: A single transaction is performed repeatedly, once per trigger, until the DMA channel is disabled. * Repeated Continuous: A series of transactions are performed repeatedly, one cycle per trigger, until the DMA channel is disabled. All transfer modes allow the option to have the source and destination addresses, and counter value, automatically reloaded after the completion of a transaction. 8.1.5 ADDRESSING MODES The DMA Controller also supports transfers between single addresses or address ranges. The four basic options are: * Fixed-to-Fixed: Between two constant addresses * Fixed-to-Block: From a constant source address to a range of destination addresses * Block-to-Fixed: From a range of source addresses to a single, constant destination address * Block-to-Block: From a range of source addresses to a range of destination addresses The option to select auto-increment or auto-decrement of source and/or destination addresses is available for Block Addressing modes. In addition to the four basic modes, the DMA Controller also supports Peripheral Indirect Addressing (PIA) mode, where the source or destination address is generated jointly by the DMA Controller and a PIA-capable peripheral. When enabled, the DMA channel provides a base source and/or destination address, while the peripheral provides a fixed range offset address.

When access collisions occur, the DMA Controller arbitrates between the channels using a user-selectable priority scheme. Two schemes are available: The channels of the DMA Controller can be individually powered down using the Peripheral Module Disable (PMD) registers. * Round Robin: When two or more channels collide, the lower numbered channel receives priority on the first collision. On subsequent collisions, the higher numbered channels each receive priority based on their channel number. * Fixed: When two or more channels collide, the lowest numbered channel always receives priority, regardless of past history; however, any channel being actively processed is not available for an immediate retrigger. If a higher priority channel is continually requesting service, it will be scheduled for service after the next lower priority channel with a pending request. The DMA Controller uses a number of registers to control its operation. The number of registers depends on the number of channels implemented for a particular device. 8.2 * DMACHn: DMA Channel n Control Register (Register 8-2) * DMAINTn: DMA Channel n Interrupt Register (Register 8-3) * DMASRCn: DMA Data Source Address Pointer for Channel n Register * DMADSTn: DMA Data Destination Source for Channel n Register * DMACNTn: DMA Transaction Counter for Channel n Register Typical Setup To set up a DMA channel for a basic data transfer: 1. Enable the DMA Controller (DMAEN = 1) and select an appropriate channel priority scheme by setting or clearing PRSSEL. 2. Program DMAH and DMAL with appropriate upper and lower address boundaries for data RAM operations. 3. Select the DMA channel to be used and disable its operation (CHEN = 0). 4. Program the appropriate source and destination addresses for the transaction into the channel's DMASRCn and DMADSTn registers. For PIA mode addressing, use the base address value. 5. Program the DMACNTn register for the number of triggers per transfer (One-Shot or Continuous modes) or the number of words (bytes) to be transferred (Repeated modes). 6. Set or clear the SIZE bit to select the data size. 7. Program the TRMODE<1:0> bits to select the Data Transfer mode. 8. Program the SAMODE<1:0> and DAMODE<1:0> bits to select the addressing mode. 9. Enable the DMA channel by setting CHEN. 10. Enable the trigger source interrupt. 2017-2018 Microchip Technology Inc. 8.4 Registers There are always four module-level registers (one control and three buffer/address): * DMACON: DMA Engine Control Register (Register 8-1) * DMAH and DMAL: DMA High and Low Address Limit Registers * DMABUF: DMA Transfer Data Buffer Each of the DMA channels implements five registers (two control and three buffer/address): For dsPIC33CH128MP508 devices, there are a total of 34 registers.

It is not intended to be a comprehensive reference source. For more information on the MCCP/SCCP modules, refer to "Capture/Compare/ PWM/Timer (MCCP and SCCP)" (DS33035) in the "dsPIC33/PIC24 Family Reference Manual". 2: The SCCP is identical for both Master core and Slave core. The x is common for both Master and Slave (where the x represents the number of the specific module being addressed). 3: All associated register names are the same on the Master core and the Slave core. The Slave code will be developed in a separate project in MPLAB(R) X IDE with the device selection, dsPIC33CH128MP508S1, where S1 indicates the Slave device. The Master SCCP modules are SCCP1, SCCP2, SCCP3, SCCP4, SSCCP5, SCCP6, SCCP7 and SCCP8. The Slave SCCP modules are SCCP1, SCCP2, SCCP3 and SCCP4. Table 10-1 shows an overview of the SCCP module. TABLE 10-1: SCCP MODULE OVERVIEW Number of SCCP Modules Identical (Modules) Master Core 8 Yes Slave Core 4 Yes 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 family devices include several Capture/Compare/PWM/Timer base modules, which provide the functionality of three different peripherals from earlier PIC24F devices. The module can operate in one of three major modes: * General Purpose Timer * Input Capture * Output Compare/PWM Single CCP (SCCP) output modules provide only one PWM output. The SCCP module can be operated only in one of the three major modes at any time. The other modes are not available unless the module is reconfigured for the new mode. A conceptual block diagram for the module is shown in Figure 10-1. All three modes share a time base generator and a common Timer register pair (CCPxTMRH/L); other shared hardware components are added as a particular mode requires. Each module has a total of six control and status registers: * * * * * * CCPxCON1L (Register 10-1) CCPxCON1H (Register 10-2) CCPxCON2L (Register 10-3) CCPxCON2H (Register 10-4) CCPxCON3H (Register 10-5) CCPxSTATL (Register 10-6) Each module also includes eight buffer/counter registers that serve as Timer Value registers or data holding buffers: * CCPxTMRH/CCPxTMRL (CCPx Timer High/Low Counters) * CCPxPRH/CCPxPRL (CCPx Timer Period High/Low) * CCPxRA (CCPx Primary Output Compare Data Buffer) * CCPxRB (CCPx Secondary Output Compare Data Buffer) * CCPxBUFH/CCPxBUFL (CCPx Input Capture High/Low Buffers) DS70005319B-page 535 dsPIC33CH128MP508 FAMILY FIGURE 10-1: SCCPx CONCEPTUAL BLOCK DIAGRAM CCPxIF External Capture Input CCTxIF Input Capture Sync/Trigger Out Special Trigger (to ADC) Clock Sources Time Base Generator CCPxTMRH/L Compare/PWM Output(s) T32 CCSEL MOD<3:0> Sync and Gating Sources 10.1 16/32-Bit Timer Time Base Generator The Timer Clock Generator (TCG) generates a clock for the module's internal time base, using one of the clock signals already available on the microcontroller. This is used as the time reference for the module in its three major modes. The internal time base is shown in Figure 10-2. FIGURE 10-2: Output Compare/ PWM OCFA/OCFB There are eight inputs available to the clock generator, which are selected using the CLKSEL<2:0> bits (CCPxCON1L<10:8>).

DS70005319B-page 536 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 10.2 General Purpose Timer Timer mode is selected when CCSEL = 0 and MOD<3:0> = 0000. The timer can function as a 32-bit timer or a dual 16-bit timer, depending on the setting of the T32 bit (Table 10-2). TABLE 10-2: TIMER OPERATION MODE T32 (CCPxCON1L<5>) Operating Mode 0 Dual Timer Mode (16-bit) 1 Timer Mode (32-bit) Dual 16-Bit Timer mode provides a simple timer function with two independent 16-bit timer/counters. The primary timer uses CCPxTMRL and CCPxPRL. Only the primary timer can interact with other modules on the device. It generates the SCCPx sync out signals for use by other SCCP modules. It can also use the SYNC<4:0> bits signal generated by other modules. The secondary timer uses CCPxTMRH and CCPxPRH. It is intended to be used only as a periodic interrupt source for scheduling CPU events. It does not generate an output sync/trigger signal like the primary time base. In Dual Timer mode, the CCPx Secondary Timer Period register, CCPxPRH, generates the SCCP compare event (CCPxIF) used by many other modules on the device. 10.2.1 SYNC AND TRIGGER OPERATION In both 16-bit and 32-bit modes, the timer can also function in either synchronization ("sync") or trigger operation. Both use the SYNC<4:0> bits (CCPxCON1H<4:0>) to determine the input signal source. The difference is how that signal affects the timer. In sync operation, the timer Reset or clear occurs when the input selected by SYNC<4:0> is asserted. The timer immediately begins to count again from zero unless it is held for some other reason. Sync operation is used whenever the TRIGEN bit (CCPxCON1H<7>) is cleared. SYNC<4:0> can have any value, except `11111'. In trigger operation, the timer is held in Reset until the input selected by SYNC<4:0> is asserted; when it occurs, the timer starts counting. Trigger operation is used whenever the TRIGEN bit is set. In Trigger mode, the timer will continue running after a trigger event as long as the CCPTRIG bit (CCPxSTATL<7>) is set. To clear CCPTRIG, the TRCLR bit (CCPxSTATL<5>) must be set to clear the trigger event, reset the timer and hold it at zero until another trigger event occurs. On dsPIC33CH128MP508 family devices, trigger operation can only be used when the system clock is the time base source (CLKSEL<2:0> = 000). The 32-Bit Timer mode uses the CCPxTMRL and CCPxTMRH registers, together, as a single 32-bit timer. When CCPxTMRL overflows, CCPxTMRH increments by one. This mode provides a simple timer function when it is important to track long time periods. Note that the T32 bit (CCPxCON1L<5>) should be set before the CCPxTMRL or CCPxPRH registers are written to initialize the 32-bit timer. 2017-2018 Microchip Technology Inc.

Like most PIC(R) MCU peripherals, the Output Compare x module can also generate interrupts on a compare match event. Output Compare Mode Output Compare mode compares the Timer register value with the value of one or two Compare registers, depending on its mode of operation. The Output Compare x module, on compare match events, has the ability to generate a single output transition or a train of TABLE 10-3: Table 10-3 shows the various modes available in Output Compare modes.

Output Compare Interrupt DS70005319B-page 539 dsPIC33CH128MP508 FAMILY 10.4 Input Capture Mode Input Capture mode is used to capture a timer value from an independent timer base, upon an event, on an input pin or other internal trigger source. The input capture features are useful in applications requiring frequency (time period) and pulse measurement. Figure 10-6 depicts a simplified block diagram of Input Capture mode. TABLE 10-4: Input Capture mode uses a dedicated 16/32-bit, synchronous, up counting timer for the capture function. The timer value is written to the FIFO when a capture event occurs. The internal value may be read (with a synchronization delay) using the CCPxTMRH/L register. To use Input Capture mode, the CCSEL bit (CCPxCON1L<4>) must be set. The T32 and the MOD<3:0> bits are used to select the proper Capture mode, as shown in Table 10-4.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "High-Speed Analog Comparator Module" (DS70005280) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 3.2 "Master Memory Organization" in this data sheet for device-specific register and bit information. 3: The comparator and DAC are identical for both Master core and Slave core. The module is similar for both Master core and Slave core (where the x represents the number of the specific modules being addressed in Master or Slave). The high-speed analog comparator module provides a method to monitor voltage, current and other critical signals in a power conversion application that may be too fast for the CPU and ADC to capture. There are a total of four comparator modules, one of which is controlled by the Master core and the remaining three by the Slave core. The analog comparator module can be used to implement Peak Current mode control, Critical Conduction mode (variable frequency) and Hysteretic Control mode. Table 11-1 shows an overview of the comparator/DAC module. TABLE 11-1: 11.1 The high-speed analog comparator module is comprised of a high-speed comparator, Pulse Density Modulation (PDM) DAC and a slope compensation unit. The slope compensation unit provides a userdefined slope which can be used to alter the DAC output. This feature is useful in applications, such as Peak Current mode control, where slope compensation is required to maintain the stability of the power supply. The user simply specifies the direction and rate of change for the slope compensation and the output of the DAC is modified accordingly. The DAC consists of a PDM unit, followed by a digitally controlled multiphase RC filter. The PDM unit uses a phase accumulator circuit to generate an output stream of pulses. The density of the pulse stream is proportional to the input data value, relative to the maximum value supported by the bit width of the accumulator. The output pulse density is representative of the desired output voltage. The pulse stream is filtered with an RC filter to yield an analog voltage. The output of the DAC is connected to the negative input of the comparator. The positive input of the comparator can be selected using a MUX from either of the input pins or the output of the PGAs. The comparator provides a high-speed operation with a typical delay of 15 ns. The output of the comparator is processed by the pulse stretcher and the digital filter blocks, which prevent comparator response to unintended fast transients in the inputs. Figure 11-1 shows a block diagram of the high-speed analog comparator module. The DAC module can be operated in one of three modes: Slope Generation mode, Hysteretic mode and Triangle Wave mode. Each of these modes can be used in a variety of power supply applications. Note: The DACOUT pin can only be associated with a single DAC or PGA output at any given time. If more than one DACOEN bit is set, or the PGA Output Enable bit (PGAOEN) and the DACOEN bit are set, the DACOUT pin will be a combination of the signals. Note: DAC input frequency needs to be 500 MHz. COMPARATOR/DAC MODULE OVERVIEW Number of Comparator Modules Identical (Modules) Master Core 1 Yes Slave Core 3 Yes 2017-2018 Microchip Technology Inc.

The Master and Slave DAC modules are controlled by separate sets of DACCTRL1/2 registers. The DACxCON, DACxDAT, SLPxCON and SLPxDAT registers specify the operation of individual modules. Note that x = 1 for the Master module and x = 1-3 for the Slave modules.

Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive resource. For more information, refer to the "Quadrature Encoder Interface (QEI)" (DS70000601) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The two channels, Phase A (QEAx) and Phase B (QEBx), are typically 90 degrees out of phase with respect to each other. The Phase A and Phase B channels have a unique relationship. If Phase A leads Phase B, the direction of the motor is deemed positive or forward. If Phase A lags Phase B, the direction of the motor is deemed negative or reverse. The Index pulse occurs once per mechanical revolution and is used as a reference to indicate an absolute position. Figure 12-1 illustrates the Quadrature Encoder Interface signals. 2: The QEI is identical for both Master core and Slave core (the x represents the number of the specific module being addressed in Master or Slave). The Quadrature signals from the encoder can have four unique states (`01', `00', `10' and `11') that reflect the relationship between QEAx and QEBx. Figure 12-1 illustrates these states for one count cycle. The order of the states get reversed when the direction of travel changes. 3: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 3.2 "Master Memory Organization" in this data sheet for device-specific register and bit information. The Quadrature Decoder increments or decrements the 32-bit up/down Position x Counter (POSxCNTH/L) registers for each Change-of-State (COS). The counter increments when QEAx leads QEBx and decrements when QEBx leads QEAx. Table 12-1 shows an overview of the QEI module. The Quadrature Encoder Interface (QEI) module provides the interface to incremental encoders for obtaining mechanical position data. Quadrature Encoders, also known as incremental encoders or optical encoders, detect position and speed of rotating motion systems. Quadrature Encoders enable closed-loop control of motor control applications, such as Switched Reluctance (SR) and AC Induction Motors (ACIM). TABLE 12-1: A typical Quadrature Encoder includes a slotted wheel attached to the shaft of the motor and an emitter/ detector module that senses the slots in the wheel.

The QEI module consists of decoder logic to interpret the Phase A (QEAx) and Phase B (QEBx) signals, and an up/down counter to accumulate the count. The counter pulses are generated when the Quadrature state changes. The count direction information must be maintained in a register until a direction change is detected. The module also includes digital noise filters, which condition the input signal. DS70005319B-page 566 2017-2018 Microchip Technology Inc. 2017-2018 Microchip Technology Inc.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Multiprotocol Universal Asynchronous Receiver Transmitter (UART) Module" (DS70005288) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: The UART is identical for both Master core and Slave core. The x is common for both Master core and Slave core (where the x represents the number of the specific module being addressed). The number of UART modules available on the Master core and Slave core is different and they are located in different SFR locations. 3: All associated register names are the same on the Master core and the Slave core. The Slave code will be developed in a separate project in MPLAB(R) X IDE with the device selection, dsPIC33CH128MP508S1, where the S1 indicates the Slave device. The Master UART is UART1 and UART2, and the Slave UART is UART1. The Universal Asynchronous Receiver Transmitter (UART) is a flexible serial communication peripheral used to interface dsPIC(R) microcontrollers with other equipment, including computers and peripherals. The UART is a full-duplex, asynchronous communication channel that can be used to implement protocols, such as RS-232 and RS-485. The UART also supports the following hardware extensions: * * * * LIN/J2602 IrDA(R) Direct Matrix Architecture (DMX) Smart Card The primary features of the UART are: * Full or Half-Duplex Operation * Up to 8-Deep TX and RX First In, First Out (FIFO) Buffers * 8-Bit or 9-Bit Data Width * Configurable Stop Bit Length * Flow Control * Auto-Baud Calibration * Parity, Framing and Buffer Overrun Error Detection * Address Detect * Break Transmission * Transmit and Receive Polarity Control * Manchester Encoder/Decoder * Operation in Sleep mode * Wake from Sleep on Sync Break Received Interrupt Table 13-1 shows an overview of the module.

DS70005319B-page 583 dsPIC33CH128MP508 FAMILY 13.1 Architectural Overview The UART transfers bytes of data, to and from device pins, using First-In First-Out (FIFO) buffers up to eight bytes deep. The status of the buffers and data is made available to user software through Special Function FIGURE 13-1: Registers (SFRs). The UART implements multiple interrupt channels for handling transmit, receive and error events. A simplified block diagram of the UART is shown in Figure 13-1. SIMPLIFIED UARTx BLOCK DIAGRAM Clock Inputs Baud Rate Generator Data Bus SFRs Interrupts Interrupt Generation TX Buffer, UxTXREG TX RX Buffer, UxRXREG RX UxDSR UxRTS Hardware Flow Control Error and Event Detection DS70005319B-page 584 UxCTS UxDTR 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 13.2 Character Frame A typical UART character frame is shown in Figure 13-2. The Idle state is high with a `Start' condition indicated by a falling edge. The Start bit is followed by the number of data, parity/address detect and Stop bits defined by the MOD<3:0> (UxMODE<3:0>) bits selected. FIGURE 13-2: UART CHARACTER FRAME Idle Idle Start Bit 13.3 D0 D1 D2 D3 Data Buffers Both transmit and receive functions use buffers to store data shifted to/from the pins. These buffers are FIFOs and are accessed by reading the SFRs, UxTXREG and UxRXREG, respectively. Each data buffer has multiple flags associated with its operation to allow software to read the status. Interrupts can also be configured based on the space available in the buffers. The transmit and receive buffers can be cleared and their pointers reset using the associated TX/RX Buffer Empty Status bits, UTXBE (UxSTAH<5>) and URXBE (UxSTAH<1>). 2017-2018 Microchip Technology Inc. D4 D5 D6 13.4 D7 Parity/ Address Stop Detect Bit(s) Protocol Extensions The UART provides hardware support for LIN/J2602, IrDA(R), DMX and smart card protocol extensions to reduce software overhead. A protocol extension is enabled by writing a value to the MOD<3:0> (UxMODE<3:0>) selection bits and further configured using the UARTx Timing Parameter registers, UxP1 (Register 13-9), UxP2 (Register 13-10), UxP3 (Register 13-11) and UxP3H (Register 13-12). Details regarding operation and usage are discussed in their respective chapters. Not all protocols are available on all devices.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Serial Peripheral Interface (SPI) with Audio Codec Support" (DS70005136) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: The SPI is Identical for both Master core and Slave core. The x is common for both Master and Slave (where the x represents the number of the specific module being addressed). The number of SPI modules available on the Master and Slave is different and they are located in different SFR locations. 3: All associated register names are the same on the Master core and the Slave core. The Slave code will be developed in a separate project in MPLAB(R) X IDE with the device selection, dsPIC33CH128MP508S1, where the S1 indicates the Slave device. The Master is SPI1 and SPI2, and the Slave is SPI1. Table 14-1 shows an overview of the SPI module. TABLE 14-1: SPI MODULE OVERVIEW Number of SPI Modules Identical (Modules) Master Core 2 Yes Slave Core 1 Yes The Serial Peripheral Interface (SPI) module is a synchronous serial interface, useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be serial EEPROMs, shift registers, display drivers, A/D Converters, etc. The SPI module is compatible with the Motorola(R) SPI and SIOP interfaces. All devices in the dsPIC33CH128MP508 family include three SPI modules; two SPIs for the Master core and one for the Slave core. One of the SPI modules can work up to 50 MHz speed when selected as a non-PPS pin. For the Master core, it will be SPI2 and for the Slave core, it will be SPI1. The selection is done using the SPI2PIN bit (FDEVOPT<13>) for the Master and the S1SPI1PIN bit (FS1DEVOPT<13>) for the Slave. If the bit for SPI2PIN/S1SPI1PIN is `1', the PPS pin will be used. If the SPI2PIN/S1SPI1PIN is `0', it will use the dedicated SPI pads. 2017-2018 Microchip Technology Inc. The module supports operation in two Buffer modes. In Standard mode, data is shifted through a single serial buffer. In Enhanced Buffer mode, data is shifted through a FIFO buffer. The FIFO level depends on the configured mode. Note: FIFO depth for this device is four (in 8-Bit Data mode). Variable length data can be transmitted and received, from 2 to 32 bits. Note: Do not perform Read-Modify-Write operations (such as bit-oriented instructions) on the SPIxBUF register in either Standard or Enhanced Buffer mode. The module also supports a basic framed SPI protocol while operating in either Master or Slave mode. A total of four framed SPI configurations are supported. The module also supports Audio modes. Four different Audio modes are available. * I2S mode * Left Justified mode * Right Justified mode * PCM/DSP mode In each of these modes, the serial clock is free-running and audio data is always transferred. If an audio protocol data transfer takes place between two devices, then usually one device is the Master and the other is the Slave. However, audio data can be transferred between two Slaves. Because the audio protocols require free-running clocks, the Master can be a third-party controller. In either case, the Master generates two free-running clocks: SCKx and LRC (Left, Right Channel Clock/SSx/FSYNC). The SPI serial interface consists of four pins: * SDIx/S1SDIx: Serial Data Input * SDOx/S1SDOx: Serial Data Output * SCKx/S1SCKx: Shift Clock Input or Output * SSx/S1SSx: Active-Low Slave Select or Frame Synchronization I/O Pulse The SPI module can be configured to operate using two, three or four pins. In the 3-pin mode, SSx/S1SSx is not used. In the 2-pin mode, both SDOx/S1SDOx and SSx/S1SSx are not used. DS70005319B-page 605 dsPIC33CH128MP508 FAMILY The SPI module has the ability to generate three interrupts reflecting the events that occur during the data communication. The following types of interrupts can be generated: 1. Receive interrupts are signalled by SPIxRXIF. This event occurs when: - RX watermark interrupt - SPIROV = 1 - SPIRBF = 1 - SPIRBE = 1 provided the respective mask bits are enabled in SPIxIMSKL/H. 2. Transmit interrupts are signalled by SPIxTXIF. This event occurs when: - TX watermark interrupt - SPITUR = 1 - SPITBF = 1 - SPITBE = 1 provided the respective mask bits are enabled in SPIxIMSKL/H. 3. General interrupts are signalled by SPIxGIF. This event occurs when: - FRMERR = 1 - SPIBUSY = 1 - SRMT = 1 provided the respective mask bits are enabled in SPIxIMSKL/H. Block diagrams of the module in Standard and Enhanced modes are shown in Figure 14-1 and Figure 14-2. Note: In this section, the SPI modules are referred to together as SPIx, or separately as SPI1, SPI2 or SPI3. Special Function Registers will follow a similar notation. For example, SPIxCON1 and SPIxCON2 refer to the control registers for any of the three SPI modules.

DS70005319B-page 622 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 15.0 INTER-INTEGRATED CIRCUIT (I2C) Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. For more information, refer to "Inter-Integrated Circuit (I2C)" (DS70000195) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: The I2C is identical for both Master core and Slave core. The x is common for both Master and Slave (where the x represents the number of the specific module being addressed). The number of I2C modules available on the Master and Slave is different and they are located in different SFR locations. 3: All associated register names are the same on the Master core and the Slave core. The Slave code will be developed in a separate project in MPLAB(R) X IDE with the device selection, dsPIC33CH128MP508S1, where the S1 indicates the Slave device. The Master I2C is I2C1 and I2C2, and the Slave is I2C1. The Inter-Integrated Circuit (I2C) module is a serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be serial EEPROMs, display drivers, A/D Converters, etc. 15.1 Communicating as a Master in a Single Master Environment The details of sending a message in Master mode depends on the communication protocol for the device being communicated with. Typically, the sequence of events is as follows: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. Assert a Start condition on SDAx and SCLx. Send the I 2C device address byte to the Slave with a write indication. Wait for and verify an Acknowledge from the Slave. Send the first data byte (sometimes known as the command) to the Slave. Wait for and verify an Acknowledge from the Slave. Send the serial memory address low byte to the Slave. Repeat Steps 4 and 5 until all data bytes are sent. Assert a Repeated Start condition on SDAx and SCLx. Send the device address byte to the Slave with a read indication. Wait for and verify an Acknowledge from the Slave.

The actual clock rate can be affected by various system-level parameters. The actual clock rate should be measured in its intended application. 3: Typical value of delay varies from 110 ns to 150 ns. 4: I2CxBRG values of 0 to 3 are expressly forbidden. The user should never program the I2CxBRG with a value of 0x0, 0x1, 0x2 or 0x3 as indeterminate results may occur. TABLE 15-1: Note 1: 2: Slave Address Masking The I2CxMSK register (Register 15-4) designates address bit positions as "don't care" for both 7-Bit and 10-Bit Addressing modes. Setting a particular bit location (= 1) in the I2CxMSK register causes the Slave module to respond, whether the corresponding address bit value is a `0' or a `1'. For example, when I2CxMSK is set to `0010000000', the Slave module will detect both addresses, `0000000000' and `0010000000'. To enable address masking, the Intelligent Peripheral Management Interface (IPMI) must be disabled by clearing the STRICT bit (I2CxCONL<11>). Note: As a result of changes in the I2C protocol, the addresses in Table 15-2 are reserved and will not be Acknowledged in Slave mode. This includes any address mask settings that include any of these addresses.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Single-Edge Nibble Transmission (SENT) Module" (DS70005145) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 3.2 "Master Memory Organization" in this data sheet for device-specific register and bit information. SENT protocol timing is based on a predetermined time unit, TTICK. Both the transmitter and receiver must be preconfigured for TTICK, which can vary from 3 to 90 s. A SENT message frame starts with a Sync pulse. The purpose of the Sync pulse is to allow the receiver to calculate the data rate of the message encoded by the transmitter. The SENT specification allows messages to be validated with up to a 20% variation in TTICK. This allows for the transmitter and receiver to run from different clocks that may be inaccurate, and drift with time and temperature. The data nibbles are four bits in length and are encoded as the data value + 12 ticks. This yields a 0 value of 12 ticks and the maximum value, 0xF, of 27 ticks. A SENT message consists of the following: Table 16-1 shows an overview of the SENT module. * A synchronization/calibration period of 56 tick times * A status nibble of 12-27 tick times * Up to six data nibbles of 12-27 tick times * A CRC nibble of 12-27 tick times * An optional pause pulse period of 12-768 tick times TABLE 16-1: Figure 16-1 shows a block diagram of the SENTx module. 3: This SENT module is available only on the Master.

Module Introduction The Single-Edge Nibble Transmission (SENT) module is based on the SAE J2716, "SENT - Single-Edge Nibble Transmission for Automotive Applications". The SENT protocol is a one-way, single wire time modulated serial communication, based on successive falling edges. It is intended for use in applications where high-resolution sensor data needs to be communicated from a sensor to an Engine Control Unit (ECU). The SENTx module has the following major features: * * * * * * * * * Selectable Transmit or Receive mode Synchronous or Asynchronous Transmit modes Automatic Data Rate Synchronization Optional Automatic Detection of CRC Errors in Receive mode Optional Hardware Calculation of CRC in Transmit mode Support for Optional Pause Pulse Period Data Buffering for One Message Frame Selectable Data Length for Transmit/Receive from Three to Six Nibbles Automatic Detection of Framing Errors 2017-2018 Microchip Technology Inc.

The module can be configured for continuous asynchronous message frame transmission, or alternatively, for Synchronous mode triggered by software. When enabled, the transmitter will send a Sync, followed by the appropriate number of data nibbles, an optional CRC and optional pause pulse. The tick period used by the SENTx transmitter is set by writing a value to the TICKTIME<15:0> (SENTxCON2<15:0>) bits. The tick period calculations are shown in Equation 16-1. EQUATION 16-1: TICK PERIOD CALCULATION TICKTIME<15:0> = TTICK -1 TCLK An optional pause pulse can be used in Asynchronous mode to provide a fixed message frame time period. The frame period used by the SENTx transmitter is set by writing a value to the FRAMETIME<15:0> (SENTxCON3<15:0>) bits. The formulas used to calculate the value of frame time are shown in Equation 16-2. EQUATION 16-2: FRAME TIME CALCULATIONS FRAMETIME<15:0> = TTICK/TFRAME FRAMETIME<15:0> 122 + 27N FRAMETIME<15:0> 848 + 12N 16.2.1.1 TRANSMIT MODE CONFIGURATION Initializing the SENTx Module Perform the following steps to initialize the module: 1. Write RCVEN (SENTxCON1<11>) = 0 for Transmit mode. 2. Write TXM (SENTxCON1<10>) = 0 for Asynchronous Transmit mode or TXM = 1 for Synchronous mode. 3. Write NIBCNT<2:0> (SENTxCON1<2:0>) for the desired data frame length. 4. Write CRCEN (SENTxCON1<8>) for hardware or software CRC calculation. 5. Write PPP (SENTxCON1<7>) for optional pause pulse. 6. If PPP = 1, write TFRAME to SENTxCON3. 7. Write SENTxCON2 with the appropriate value for the desired tick period. 8. Enable interrupts and set interrupt priority. 9. Write initial status and data values to SENTxDATH/L. 10. If CRCEN = 0, calculate CRC and write the value to CRC<3:0> (SENTxDATL<3:0>). 11. Set the SNTEN (SENTxCON1<15>) bit to enable the module. User software updates to SENTxDATH/L must be performed after the completion of the CRC and before the next message frame's status nibble. The recommended method is to use the message frame completion interrupt to trigger data writes. Where: TFRAME = Total time of the message from ms N = The number of data nibbles in message, 1-6 Note: The module will not produce a pause period with less than 12 ticks, regardless of the FRAMETIME<15:0> value. FRAMETIME<15:0> values beyond 2047 will have no effect on the length of a data frame. 2017-2018 Microchip Technology Inc. DS70005319B-page 635 dsPIC33CH128MP508 FAMILY 16.3 Receive Mode 16.3.1 The module can be configured for receive operation by setting the RCVEN (SENTxCON1<11>) bit. The time between each falling edge is compared to SYNCMIN<15:0> (SENTxCON3<15:0>) and SYNCMAX<15:0> (SENTxCON2<15:0>), and if the measured time lies between the minimum and maximum limits, the module begins to receive data. The validated Sync time is captured in the SENTxSYNC register and the tick time is calculated. Subsequent falling edges are verified to be within the valid data width and the data is stored in the SENTxDATL/H registers. An interrupt event is generated at the completion of the message and the user software should read the SENTx Data registers before the reception of the next nibble. The equation for SYNCMIN<15:0> and SYNCMAX<15:0> is shown in Equation 16-3. EQUATION 16-3: 16.3.1.1 Initializing the SENTx Module Perform the following steps to initialize the module: 1. 2. 3. 4. 5. 6. 7. 8. SYNCMIN<15:0> AND SYNCMAX<15:0> CALCULATIONS RECEIVE MODE CONFIGURATION Write RCVEN (SENTxCON1<11>) = 1 for Receive mode. Write NIBCNT<2:0> (SENTxCON1<2:0>) for the desired data frame length. Write CRCEN (SENTxCON1<8>) for hardware or software CRC validation. Write PPP (SENTxCON1<7>) = 1 if pause pulse is present. Write SENTxCON2 with the value of SYNCMAXx (Nominal Sync Period + 20%). Write SENTxCON3 with the value of SYNCMINx (Nominal Sync Period - 20%). Enable interrupts and set interrupt priority. Set the SNTEN (SENTxCON1<15>) bit to enable the module. The data should be read from the SENTxDATL/H registers after the completion of the CRC and before the next message frame's status nibble. The recommended method is to use the message frame completion interrupt trigger. TTICK = TCLK * (TICKTIME<15:0> + 1) FRAMETIME<15:0> = TTICK/TFRAME SyncCount = 8 x FRCV x TTICK SYNCMIN<15:0> = 0.8 x SyncCount SYNCMAX<15:0> = 1.2 x SyncCount FRAMETIME<15:0> 122 + 27N FRAMETIME<15:0> 848 + 12N Where: TFRAME = Total time of the message from ms N = The number of data nibbles in message, 1-6 FRCV = FCY x Prescaler TCLK = FCY/Prescaler For TTICK = 3.0 s SYNCMIN<15:0> = 76. Note: and FCLK = 4 MHz, To ensure a Sync period can be identified, the value written to SYNCMIN<15:0> must be less than the value written to SYNCMAX<15:0>.

FIGURE 18-1: The Configurable Logic Cell (CLC) module allows the user to specify combinations of signals as inputs to a logic function and to use the logic output to control other peripherals or I/O pins. This provides greater flexibility and potential in embedded designs, since the CLC module can operate outside the limitations of software execution, and supports a vast amount of output designs. There are four input gates to the selected logic function. These four input gates select from a pool of up to 32 signals that are selected using four data source selection multiplexers.

Each multiplexer has a list of eight data sources available. The CLCx module is controlled by the following registers: * * * * * CLCxCONL CLCxCONH CLCxSEL CLCxGLSL CLCxGLSH The CLCx Gate Logic Input Select registers (CLCxGLSL and CLCxGLSH) allow the user to select which outputs from each of the selection MUXes are used as inputs to the input gates of the logic cell. Each data source MUX outputs both a true and a negated version of its output. All of these eight signals are enabled, ORed together by the logic cell input gates. The CLCx Control registers (CLCxCONL and CLCxCONH) are used to enable the module and interrupts, control the output enable bit, select output polarity and select the logic function.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the related section of the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The dsPIC33CH128MP508 family devices include several features intended to maximize application flexibility and reliability, and minimize cost through elimination of external components. These are: * * * * * * * Flexible Configuration Watchdog Timer (WDT) Code Protection and CodeGuardTM Security JTAG Boundary Scan Interface In-Circuit Serial ProgrammingTM (ICSPTM) In-Circuit Emulation Brown-out Reset (BOR) 21.1 Configuration Bits In dsPIC33CH128MP508 family devices, the Configuration Words are implemented as volatile memory. This means that configuration data will get loaded to volatile memory (from the Flash Configuration Words) each time the device is powered up. Configuration data is stored at the end of the on-chip program memory space, known as the Flash Configuration Words. Their specific locations are shown in Table 21-1. The configuration data is automatically loaded from the Flash Configuration Words to the proper Configuration Shadow registers during device Resets. Note: Configuration data is reloaded on all types of device Master Resets. Slave Resets do not load the Configuration registers. It is recommended not to change the Slave Configuration register without resetting the Slave along with the Master (S1MSRE = 1). When creating applications for these devices, users should always specifically allocate the location of the Flash Configuration Words for configuration data in their code for the compiler. This is to make certain that program code is not stored in this address when the code is compiled. Program code executing out of configuration space will cause a device Reset. The Master code, as well as the Slave code, are located in Flash memory. Table 21-1 shows the Master and the Slave Configuration registers and their address locations in Flash memory. 2017-2018 Microchip Technology Inc. Slave Configuration bits are located in the Master Flash and loaded during a Master Reset. Note: Performing a page erase operation on the last page of program memory clears the Flash Configuration Words.

These registers are used to determine the mask, variant and manufacturing information about the device. These registers are read-only and are shown in Register 21-32 and Register 21-33. The PGAx and current source modules on the dsPIC33CH128MP508 family devices require Calibration Data registers to improve performance of the module over a wide operating range. These Calibration registers are read-only and are stored in configuration memory space. Prior to enabling the module, the calibration data must be read (TBLPAG and Table Read instruction) and loaded into their respective SFR registers.

Each 48-bit OTP double word can only be written one time. The OTP Words can be used for storing checksums, code revisions, manufacturing dates, manufacturing lot numbers or any other application-specific information. FIGURE 21-1: The OTP area is not cleared by any erase command. This memory can be written only once. 21.4 On-Chip Voltage Regulators All of the dsPIC33CH128MP508 family devices have a capacitorless, internal voltage regulator to supply power to the core at 1.2V (typical). A pair of voltage regulators, VREG1 and VREG2 together, provide power for the core. The PLL is powered using a separate regulator, VREGPLL, as shown in Figure 21-1.

AVSS Band Gap Reference DS70005319B-page 701 dsPIC33CH128MP508 FAMILY 21.5 Regulator Control and Sleep Mode As shown in Figure 21-1, both VREG1 and VREG2 together, share the total load for the Master and Slave. The PLL for the Master and Slave is powered using a separate regulator, as shown for VREG3 (VREGPLL). The output voltages of these regulators can be controlled by the user, which gives eligibility to save power during Sleep mode. As shown in Register 21-34, there are two control bits, VREGxOV<1:0>, to control the output voltages of these regulators. VREGCON<15> should be set to put the regulator in Low-Power mode before going to Sleep. Before going to Sleep, the voltage regulator should be changed to 1V (or 0.8V). The voltage regulators communicate to the Slave or Master depending on the scenario below.

The main purpose of the BOR module is to generate a device Reset when a brown-out condition occurs. Brown-out conditions are generally caused by glitches on the AC mains (for example, missing portions of the AC cycle waveform due to bad power transmission lines or voltage sags due to excessive current draw when a large inductive load is turned on). A BOR generates a Reset pulse which resets the device. The BOR selects the clock source based on the device Configuration bit selections. 2017-2018 Microchip Technology Inc. If an Oscillator mode is selected, the BOR activates the Oscillator Start-up Timer (OST). The system clock is held until OST expires. If the PLL is used, the clock is held until the LOCK bit (OSCCON<5>) is `1'. Concurrently, the PWRT Time-out (TPWRT) is applied before the internal Reset is released. If TPWRT = 0 and a crystal oscillator is being used, then a nominal delay of TFSCM is applied. The total delay in this case is TFSCM. Refer to Parameter SY35 in Table 24-32 of Section 24.0 "Electrical Characteristics" for specific TFSCM values. The BOR status bit (RCON<1>) is set to indicate that a BOR has occurred. The BOR circuit continues to operate while in Sleep or Idle mode and resets the device should VDD fall below the BOR threshold voltage. DS70005319B-page 703 dsPIC33CH128MP508 FAMILY 21.7 Dual Watchdog Timer (WDT) Note 1: This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to "Dual Watchdog Timer", (DS70005250) in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: The WDT is identical for both Master core and Slave core. The x is common for both Master core and Slave core (where the x represents the number of the specific module being addressed). The number of WDT modules available on the Master and Slaves is different and they are located in different SFR locations. 3: All associated register names are the same on the Master core and the Slave core. The Slave code will be developed in a separate project in MPLAB(R) X IDE with the device selection, dsPIC33CH128MP508S1, where the S1 indicates the Slave device. Table 21-6 shows an overview of the WDT module. TABLE 21-6: DUAL WDT MODULE OVERVIEW Number of WDT Modules Identical (Modules) Master Core 1 Yes Slave Core 1 Yes The dsPIC33 dual Watchdog Timer (WDT) is described in this section. Refer to Figure 21-2 for a block diagram of the WDT. The WDT, when enabled, operates from the internal Low-Power RC (LPRC) Oscillator clock source or a selectable clock source in Run mode. The WDT can be used to detect system software malfunctions by resetting the device if the WDT is not cleared periodically in software. The WDT can be configured in Windowed mode or Non-Windowed mode. Various WDT time-out periods can be selected using the WDT postscaler. The WDT can also be used to wake the device from Sleep or Idle mode (Power Save mode). If the WDT expires and issues a device Reset, the WTDO bit of the RCON register (Register 21-37) will be set. The following are some of the key features of the WDT modules: * Configuration or Software Controlled * Separate User-Configurable Time-out Periods for Run and Sleep/Idle * Can Wake the Device from Sleep or Idle * User-Selectable Clock Source in Run mode * Operates from LPRC in Sleep/Idle mode Note: DS70005319B-page 704 While executing a clock switch, the WDT will not be reset. It is recommended to reset the WDT prior to executing a clock switch instruction. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY FIGURE 21-2: WATCHDOG TIMER BLOCK DIAGRAM Power Save Mode WDT LPRC Oscillator 32-Bit Counter Power Save CLKSEL<1:0> FCY (FOSC/2) Reserved FRC Oscillator LPRC Oscillator ON Power Save Wake-up and NMI Comparator Reset SLPDIV<4:0> Run Mode WDT 00 01 Power Save 32-Bit Counter NMI and Start NMI Counter Comparator 10 11 Reset RUNDIV<4:0> WDTCLRKEY<15:0> = 5743h ON All Resets Clock Switch 2017-2018 Microchip Technology Inc.

DS70005319B-page 709 dsPIC33CH128MP508 FAMILY 21.9 JTAG Interface The dsPIC33CH128MP508 family devices implement a JTAG interface, which supports boundary scan device testing. Detailed information on this interface will be provided in future revisions of this document. Note: 21.10 Refer to "Programming and Diagnostics" (DS70608) in the "dsPIC33/PIC24 Family Reference Manual" for further information on usage, configuration and operation of the JTAG interface. In-Circuit Serial ProgrammingTM (ICSPTM) The dsPIC33CH128MP508 family devices can be serially programmed while in the end application circuit. This is done with two lines for clock and data, and three other lines for power, ground and the programming sequence. Serial programming allows customers to manufacture boards with unprogrammed devices and then program the device just before shipping the product. Serial programming also allows the most recent firmware or a custom firmware to be programmed. Refer to the "dsPIC33CH128MP508 Family Flash Programming Specification" (DS70005285) for details about In-Circuit Serial Programming (ICSP). Any of the three pairs of programming clock/data pins can be used: * PGC1 and PGD1 * PGC2 and PGD2 * PGC3 and PGD3 Note: Both Master core and Slave core can be used with MPLAB(R) ICD to debug at the same time. There are PGCx and PGDx pins dedicated for the Master core and Slave core (S1PGCx and S1PGDx) to make this possible. MCLR is the same for programming the Master core and the Slave core. S1MCLRx is used only when the Master and Slave are debugged simultaneously. 21.11 In-Circuit Debugger When MPLAB(R) ICD 3 or the REAL ICETM emulator is selected as a debugger, the in-circuit debugging functionality is enabled. This function allows simple debugging functions when used with MPLAB IDE. Debugging functionality is controlled through the PGCx (Emulation/Debug Clock) and PGDx (Emulation/Debug Data) pin functions. Any of the three pairs of debugging clock/data pins can be used: * PGC1 and PGD1 Master Debug or Slave Debug * PGC2 and PGD2 Master Debug or Slave Debug * PGC3 and PGD3 Master Debug or Slave Debug for debugging Master and Slave simultaneously, two MPLAB ICD debuggers or the REAL ICETM emulator are required. This mode of debugging, where the Master and Slave are simultaneously debugged, is called the Dual Debug mode. S1MCLRx and S1PGCx/S1PGDx are used only in Dual Debug mode. The Dual Debug mode of operation needs the following PGCx/PGDx pins: * MCLR, PGC1 and PGD1 for Master Debug, and S1MCLR1, S1PGC1 and S1PGD1 for Slave Debug * MCLR, PGC2 and PGD2 for Master Debug, and S1MCLR2, S1PGC2 and S1PGD2 for Slave Debug * MCLR, PGC3 and PGD3 for Master Debug, and S1MCLR3, S1PGC3 and S1PGD3 for Slave Debug To use the in-circuit debugger function of the device, the design must implement ICSP connections to MCLR, VDD, VSS and the PGCx/PGDx pin pair. In addition, when the feature is enabled, some of the resources are not available for general use. These resources include the first 80 bytes of data RAM and two or five (in Dual Debug) I/O pins (PGCx and PGDx). There are three modes of debugging the dual core family of dsPIC33CH128MP508: 1. 2. 3. Master Only Debug Slave Only Debug Dual Debug 21.11.1 MASTER ONLY DEBUG In Master Only Debug, only the Master project will be debugged. There is no project for Slave or no Slave code. The main project will be for dsPIC33CHXXXMP50X/20X and the user has to use MCLR and PGCx/PGDx for debugging. This is similar to debugging any single core existing device. DS70005319B-page 710 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 21.11.2 SLAVE ONLY DEBUG In the Slave Only Debug mode, the user will need two projects. One project is the Master project with dsPIC33CHXXXMP50X/20X as the device. This is called a Master Stub and is required to provide the configuration information to the Slave. The Slave does not have its own Configuration bits. The Configuration bits reside in the Master Flash. The Master Stub will be small code used to provide the Configuration bits for the Slave. The Master Stub is first programed to the Master Flash using MCLR, PGCx and PGDx. Once the Master Stub is programmed in the Master Flash, the user has to open a new project with dsPIC33CHXXXMP50X/20XS1 (the S1 indicates the Slave device). The same MCLR and PGCx/PGDx, or different PGCx/PGDx, can be used for debugging the Slave. Now the Slave can be debugged like any other single core device. 21.11.3 DUAL DEBUG (BOTH MASTER AND SLAVE ARE DEBUGGED) In this Debug mode, two debug tools are required: one for Master and one for Slave. In the Dual Debug mode, the user needs two projects. One project is the Master project with dsPIC33CHXXXMP50X/20X as the device. Configuration bits for the Master, as well as the Slave, will be part of this project. The S1ISOLAT bit can be set and the Master project can be debugged like any other existing single core device. The Master can be debugged using MCLR, PGCx and PGDx. Once the Master has started the debug process, the user has to open a new project with dsPIC33CHXXXMP50X/ 20XS1 (the S1 indicates the Slave device). Connect the project using S1MCLRx and S1PGCx/S1PGDx, and start debugging the Slave project. 2017-2018 Microchip Technology Inc. 21.12 Code Protection and CodeGuardTM Security - Master Flash dsPIC33CH128MP508 family devices offer multiple levels of security for protecting individual intellectual property. The program Flash protection can be broken up into three segments: Boot Segment (BS), General Segment (GS) and Configuration Segment (CS). Boot Segment has the highest security privilege and can be thought to have limited restrictions when accessing other segments. General Segment has the least security and is intended for the end user system code. Configuration Segment contains only the device user configuration data, which is located at the end of the program memory space. The code protection features are controlled by the Configuration registers, FSEC and FBSLIM. The FSEC register controls the code-protect level for each segment and if that segment is write-protected. The size of BS and GS will depend on the BSLIM<12:0> bits setting and if the Alternate Interrupt Vector Table (AIVT) is enabled. The BSLIM<12:0> bits define the number of pages for BS with each page containing 1024 IW. The smallest BS size is one page, which will consist of the Interrupt Vector Table (IVT) and 512 IW of code protection. If the AIVT is enabled, the last page of BS will contain the AIVT and will not contain any BS code. With AIVT enabled, the smallest BS size is now two pages (2048 IW), with one page for the IVT and BS code, and the other page for the AIVT. Write protection of the BS does not cover the AIVT. The last page of BS can always be programmed or erased by BS code. The General Segment will start at the next page and will consume the rest of program Flash, except for the Flash Configuration Words. The IVT will assume GS security only if BS is not enabled. The IVT is protected from being programmed or page erased when either security segment has enabled write protection. DS70005319B-page 711 dsPIC33CH128MP508 FAMILY The different device security segments are shown in Figure 21-3. Here, all three segments are shown, but are not required. If only basic code protection is required, then GS can be enabled independently or combined with CS, if desired. FIGURE 21-3: SECURITY SEGMENTS EXAMPLE 0x000000 IVT IVT and AIVT Assume BS Protection 0x000200 BS AIVT + 512 IW(2) BSLIM<12:0> GS CS(1) 0x00B000 Note 1: 2: If CS is write-protected, the last page (GS + CS) of program memory will be protected from an erase condition. The last half (256 IW) of the last page of BS is unusable program memory. DS70005319B-page 712 21.13 Code Protection and CodeGuardTM Security - Slave PRAM The dsPIC33CH128MP508S1 family Slave PRAM inherits its security configuration from the Master GSS<1:0> and GWRP Configuration bit settings. The Slave PRAM does not have a BS or CS segment. All user code space is considered GS, including the IVT. Therefore, there are no specific segment read and write permissions to consider. If either the GSSx or GWRP bits are enabled, ICSP entry directly to the Slave PRAM is inhibited. This prevents Slave only programming and debugging when the Master Flash GS is code-protected. RTSP self-programming of the PRAM is still allowed when Flash GS code protection is enabled. However, the Slave PRAM image containing the application code for the RTSP operations must be loaded from the Master Flash at run time and is subject to Master Flash code protection configuration. Master to Slave image loading is always allowed, regardless of any code protection settings. Privileged Dual Partition mode performs the same function as Protected Dual Partition mode, except additional constraints are applied in an effort to prevent code in the Boot Segment and General Segment from being used against each other. 2017-2018 Microchip Technology Inc. dsPIC33CH128MP508 FAMILY 22.0 Note: INSTRUCTION SET SUMMARY This data sheet summarizes the features of the dsPIC33CH128MP508 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the related section in the "dsPIC33/PIC24 Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The dsPIC33CH instruction set is almost identical to that of the dsPIC30F and dsPIC33F. Most instructions are a single program memory word (24 bits). Only three instructions require two program memory locations. Each single-word instruction is a 24-bit word, divided into an 8-bit opcode, which specifies the instruction type and one or more operands, which further specify the operation of the instruction. The instruction set is highly orthogonal and is grouped into five basic categories: * * * * * Word or byte-oriented operations Bit-oriented operations Literal operations DSP operations Control operations Table 22-1 lists the general symbols used in describing the instructions. The dsPIC33 instruction set summary in Table 22-2 lists all the instructions, along with the status flags affected by each instruction. Most word or byte-oriented W register instructions (including barrel shift instructions) have three operands: * The first source operand, which is typically a register `Wb' without any address modifier * The second source operand, which is typically a register `Ws' with or without an address modifier * The destination of the result, which is typically a register `Wd' with or without an address modifier However, word or byte-oriented file register instructions have two operands: * The file register specified by the value `f' * The destination, which could be either the file register `f' or the W0 register, which is denoted as `WREG' 2017-2018 Microchip Technology Inc. Most bit-oriented instructions (including simple rotate/ shift instructions) have two operands: * The W register (with or without an address modifier) or file register (specified by the value of `Ws' or `f') * The bit in the W register or file register (specified by a literal value or indirectly by the contents of register `Wb') The literal instructions that involve data movement can use some of the following operands: * A literal value to be loaded into a W register or file register (specified by `k') * The W register or file register where the literal value is to be loaded (specified by `Wb' or `f') However, literal instructions that involve arithmetic or logical operations use some of the following operands: * The first source operand, which is a register `Wb' without any address modifier * The second source operand, which is a literal value * The destination of the result (only if not the same as the first source operand), which is typically a register `Wd' with or without an address modifier The MAC class of DSP instructions can use some of the following operands: * The accumulator (A or B) to be used (required operand) * The W registers to be used as the two operands * The X and Y address space prefetch operations * The X and Y address space prefetch destinations * The accumulator write-back destination The other DSP instructions do not involve any multiplication and can include: * The accumulator to be used (required) * The source or destination operand (designated as Wso or Wdo, respectively) with or without an address modifier * The amount of shift specified by a W register `Wn' or a literal value The control instructions can use some of the following operands: * A program memory address * The mode of the Table Read and Table Write instructions DS70005319B-page 713 dsPIC33CH128MP508 FAMILY Most instructions are a single word. Certain double-word instructions are designed to provide all the required information in these 48 bits. In the second word, the 8 MSbs are `0's. If this second word is executed as an instruction (by itself), it executes as a NOP. The double-word instructions execute in two instruction cycles. Most single-word instructions are executed in a single instruction cycle, unless a conditional test is true or the Program Counter is changed as a result of the instruction, or a PSV or Table Read is performed. In TABLE 22-1: these cases, the execution takes multiple instruction cycles, with the additional instruction cycle(s) executed as a NOP. Certain instructions that involve skipping over the subsequent instruction require either two or three cycles if the skip is performed, depending on whether the instruction being skipped is a single-word or twoword instruction. Moreover, double-word moves require two cycles. Note: For more details on the instruction set, refer to the "16-Bit MCU and DSC Programmer's Reference Manual" (DS70000157).
