With 237 B of general-purpose RAM and 8 KB to 32 KB of OTP, Zilog's CMOS microcontrollers offer fast-executing, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, automated pulse generation/reception, and internal key-scan pull-up transistors. The Crimzon ZLP32300 architecture (see Figure 1 on page 3) is based on Zilog's 8-bit microcontroller core with an Expanded Register File allowing access to register-mapped peripherals, input/output (I/O) circuits, and powerful counter/timer circuitry. The Z8(R) CPU offers a flexible I/O scheme, an efficient register and address space structure, and a number of ancillary features that are useful in many consumer, automotive, computer peripheral, and battery-operated hand-held applications. There are three basic address spaces available to support a wide range of configurations: 1. Program Memory 2. Register File 3. Expanded Register File The register file is composed of 256 Bytes of RAM. It includes four I/O port registers, 16 control and status registers, and 236 general-purpose registers. The Expanded Register File consists of two additional register groups (F and D). To unburden the program from coping with such real-time problems as generating complex waveforms or receiving and demodulating complex waveform/pulses, the Crimzon ZLP32300 offers a new intelligent counter/timer architecture with 8-bit and 16-bit counter/timers (see Figure 2 on page 4). Also included are a large number of userselectable modes and two on-board comparators to process analog signals with separate reference voltages. Note: All signals with an overline, " ", are active Low. For example, B/W, in which WORD is active Low, and B/W, in which BYTE is active Low. Power connections use the conventional descriptions listed in Table 1. Table 1.

Additionally, an optional external single-phase clock can be coded to the on-chip oscillator input. XTAL2 Crystal 2 (Time-Based Output) This pin connects a parallel-resonant crystal or ceramic resonant to the on-chip oscillator output. Input/Output Ports Caution: The CMOS input buffer for each Port 0, 1, or 2 pin is always connected to the pin, even when the pin is configured as an output. If the pin is configured as an open-drain output and no external signal is applied, a High output state can cause the CMOS input buffer to float. This might lead to excessive leakage current of more than 100 A. To prevent this leakage, connect the pin to an external signal with a defined logic level or ensure its output state is Low, especially during STOP mode. Internal pull-ups are disabled on any given pin or group of port pins when programmed into output mode. Port 0, 1, and 2 have both input and output capability. The input logic is always present no matter whether the port is configured as input or output. When doing a READ instruction, the MCU reads the actual value at the input logic but not from the output buffer. In addition, the instructions of OR, AND, and XOR have the Read-Modify-Write sequence. The MCU first reads the port, and then modifies the value and load back to the port. Precaution must be taken if the port is configured as open-drain output or if the port is driving any circuit that makes the voltage different from the desired output logic. For example, pins P00-P07 are not connected to anything else. If it is configured as PS020823-0208 Pin Description Crimzon(R) ZLP32300 Product Specification 11 open-drain output with output logic as ONE, it is a floating port and reads back as ZERO. The following instruction sets P00-P07 all Low. AND P0,#%F0 Port 0 (P00-P07) Port 0 is an 8-bit, bidirectional, CMOS-compatible port. These eight I/O lines are configured under software control as a nibble I/O port. The output drivers are push-pull or opendrain controlled by bit D2 in the PCON register. If one or both nibbles are needed for I/O operation, they must be configured by writing to the Port 01 mode register (P01M). After a hardware reset or Stop Mode Recovery, Port 0 is configured as an input port. An optional pull-up transistor is available as a OTP option bit on all Port 0 bits with nibble select. Note: PS020823-0208 The Port 0 direction is reset to be input following an SMR.

Port 0 Configuration Port 1 (P17-P10) Port 1 can be configured for standard port input or output mode (see Figure 8). After POR or Stop Mode Recovery, Port 1 is configured as an input port. The output drivers are either push-pull or open-drain and are controlled by bit D1 in the PCON register. Notes: 1. The Port 1 direction is reset to be input following an SMR. 2. In 20- and 28-pin packages, Port 1 is reserved. A write to this register will have no effect and will always read FF.

Port 1 Configuration Port 2 (P27-P20) Port 2 is an 8-bit, bidirectional, CMOS-compatible I/O port (see Figure 9). These eight I/O lines can be independently configured under software control as inputs or outputs. Port 2 is always available for I/O operation. A EPROM option bit is available to connect eight pull-up transistors on this port. Bits programmed as outputs are globally programmed as either push-pull or open-drain. The POR resets with the eight bits of Port 2 configured as inputs. Port 2 also has an 8-bit input OR and AND gate, which can be used to wake up the part. P20 can be programmed to access the edge-detection circuitry in DEMODULATION mode.

Port 2 Configuration Port 3 (P37-P30) Port 3 is a 8-bit, CMOS-compatible fixed I/O port (see Figure 10). Port 3 consists of four fixed input (P33-P30) and four fixed output (P37-P34), which can be configured under software control for interrupt and as output from the counter/timers. P30, P31, P32, and P33 are standard CMOS inputs; P34, P35, P36, and P37 are push-pull outputs.

Port 3 Configuration Two on-board comparators process analog signals on P31 and P32, with reference to the voltage on Pref1 and P33. The Analog function is enabled by programming the Port 3 Mode Register (bit 1). P31 and P32 are programmable as rising, falling, or both edge triggered interrupts (IRQ register bits 6 and 7). Pref1 and P33 are the comparator reference voltage inputs. Access to the Counter Timer edge-detection circuit is through P31 or P20 PS020823-0208 Pin Description Crimzon(R) ZLP32300 Product Specification 16 (see T8 and T16 Common Functions--CTR1(0D)01h on page 28). Other edge detect and IRQ modes are described in Table 6. Note: Comparators are powered down by entering STOP mode. For P31-P33 to be used in a Stop Mode Recovery source, these inputs must be placed into DIGITAL mode. 2 Table 6.

Port 3 Counter/Timer Output Configuration PS020823-0208 Pin Description Crimzon(R) ZLP32300 Product Specification 18 Comparator Inputs In ANALOG mode, P31 and P32 have a comparator front end. The comparator reference is supplied to P33 and Pref1. In this mode, the P33 internal data latch and its corresponding IRQ1 are diverted to the SMR sources (excluding P31, P32, and P33) as displayed in Figure 10 on page 15. In DIGITAL mode, P33 is used as D3 of the Port 3 input register, which then generates IRQ1. Note: Comparators are powered down by entering STOP mode. For P31-P33 to be used in a Stop Mode Recovery source, these inputs must be placed into DIGITAL mode. Comparator Outputs These channels can be programmed to be output on P34 and P37 through the PCON register. RESET (Input, Active Low) Reset initializes the MCU and is accomplished either through Power-On, Watchdog Timer, Stop Mode Recovery, Low-Voltage detection, or external reset. During Power-On Reset and Watchdog Timer Reset, the internally generated reset drives the reset pin Low for the POR time. Any devices driving the external reset line must be open-drain to avoid damage from a possible conflict during reset conditions. Pull-up is provided internally. When the ZLP32300 asserts (Low) the RESET pin, the internal pull-up is disabled. The ZLP32300 does not assert the RESET pin when under VBO. Note: PS020823-0208 The external Reset does not initiate an exit from STOP mode.

Expanded Register File Architecture PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 23 The upper nibble of the register pointer (see Figure 14) selects which working register group, of 16 bytes in the register file, is accessed out of the possible 256. The lower nibble selects the expanded register file bank and, in the case of the Crimzon ZLP32300 family, banks 0, F, and D are implemented. A 0h in the lower nibble allows the normal register file (bank 0) to be addressed. Any other value from 1h to Fh exchanges the lower 16 registers to an expanded register bank.

Instructions can access registers directly or indirectly through an 8-bit address field, thereby allowing a short, 4-bit register address to use the Register Pointer (see Figure 15). In the 4-bit mode, the register file is divided into 16 working register groups, each occupying 16 continuous locations. The Register Pointer addresses the starting location of the active working register group. Note: PS020823-0208 Working register group E0-EF can only be accessed through working registers and indirect addressing modes.

Single/Modulo-N When set to 0 (Modulo-N), the counter reloads the initial value when the terminal count is reached. When set to 1 (single-pass), the counter stops when the terminal count is reached. Timeout This bit is set when T8 times out (terminal count reached). To reset this bit, write a 1 to its location. Caution: Writing a 1 is the only way to reset the Terminal Count status condition. Reset this bit before using/enabling the counter/timers. The first clock of T8 might not have complete clock width and can occur any time when enabled. Note: Ensure to manipulate CTR0, bit 5 and CTR1, bits 0 and 1 (DEMODULATION mode) when using the OR or AND commands. These instructions use a Read-Modify-Write sequence in which the current status from the CTR0 and CTR1 registers is ORed or ANDed with the designated value and then written back into the registers. T8 Clock These bits define the frequency of the input signal to T8. Capture_INT_Mask Set this bit to allow an interrupt when data is captured into either LO8 or HI8 upon a positive or negative edge detection in DEMODULATION mode. Counter_INT_Mask Set this bit to allow an interrupt when T8 has a timeout. P34_Out This bit defines whether P34 is used as a normal output pin or the T8 output.

Not reset with a Stop Mode Recovery. Mode If the result is 0, the counter/timers are in TRANSMIT mode; otherwise, they are in DEMODULATION mode. P36_Out/Demodulator_Input In TRANSMIT mode, this bit defines whether P36 is used as a normal output pin or the combined output of T8 and T16. In DEMODULATION mode, this bit defines whether the input signal to the Counter/Timers is from P20 or P31. If the input signal is from Port 31, a capture event may also generate an IRQ2 interrupt. To prevent generating an IRQ2, either disable the IRQ2 interrupt by clearing its IMR bit D2 or use P20 as the input. T8/T16_Logic/Edge _Detect In TRANSMIT mode, this field defines how the outputs of T8 and T16 are combined (AND, OR, NOR, NAND). In DEMODULATION mode, this field defines which edge should be detected by the edge detector. Transmit_Submode/Glitch Filter In TRANSMIT mode, this field defines whether T8 and T16 are in the PING-PONG mode or in independent normal operation mode. Setting this field to normal operation mode terminates the `PING-PONG Mode' operation. When set to 10, T16 is immediately forced to a 0; a setting of 11 forces T16 to output a 1. In DEMODULATION mode, this field defines the width of the glitch that must be filtered out. PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 31 Initial_T8_Out/Rising_Edge In TRANSMIT mode, if 0, the output of T8 is set to 0 when it starts to count. If 1, the output of T8 is set to 1 when it starts to count. When the counter is not enabled and this bit is set to 1 or 0, T8_OUT is set to the opposite state of this bit. This ensures that when the clock is enabled, a transition occurs to the initial state set by CTR1, D1. In DEMODULATION mode, this bit is set to 1 when a rising edge is detected in the input signal. In order to reset the mode, a 1 should be written to this location. Initial_T16 Out/Falling _Edge In TRANSMIT mode, if it is 0, the output of T16 is set to 0 when it starts to count. If it is 1, the output of T16 is set to 1 when it starts to count. This bit is effective only in Normal or PING-PONG mode (CTR1, D3; D2). When the counter is not enabled and this bit is set, T16_OUT is set to the opposite state of this bit. This ensures that when the clock is enabled, a transition occurs to the initial state set by CTR1, D0. In DEMODULATION mode, this bit is set to 1 when a falling edge is detected in the input signal. In order to reset it, a 1 should be written to this location. Note: Modifying CTR1 (D1 or D0) while the counters are enabled causes unpredictable output from T8/16_OUT. CTR2 Counter/Timer 16 Control Register--CTR2(D)02h Table 9 lists and briefly describes the fields for this register. Table 9.

T16_Enable This field enables T16 when set to 1. Single/Modulo-N In TRANSMIT mode, when set to 0, the counter reloads the initial value when it reaches the terminal count. When set to 1, the counter stops when the terminal count is reached. In DEMODULATION mode, when set to 0, T16 captures and reloads on detection of all the edges. When set to 1, T16 captures and detects on the first edge but ignores the subsequent edges. For details, see T16 DEMODULATION Mode on page 41. Time_Out This bit is set when T16 times out (terminal count reached). To reset the bit, write a 1 to this location. T16_Clock This bit defines the frequency of the input signal to Counter/Timer16. Capture_INT_Mask This bit is set to allow an interrupt when data is captured into LO16 and HI16. Counter_INT_Mask Set this bit to allow an interrupt when T16 times out. PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 33 P35_Out This bit defines whether P35 is used as a normal output pin or T16 output. CTR3 T8/T16 Control Register--CTR3(D)03h Table 10 lists and briefly describes the fields for this register. This register allows the T8 and T16 counters to be synchronized.

Not reset with a Stop Mode Recovery. Counter/Timer Functional Blocks Input Circuit The edge detector monitors the input signal on P31 or P20. Based on CTR1 D5-D4, a pulse is generated at the Pos Edge or Neg Edge line when an edge is detected. Glitches in the input signal that have a width less than specified (CTR1 D3, D2) are filtered out (see Figure 16).

Glitch Filter Circuitry T8 TRANSMIT Mode Before T8 is enabled, the output of T8 depends on CTR1, D1. If it is 0, T8_OUT is 1; if it is 1, T8_OUT is 0. See Figure 17.

TRANSMIT Mode Flowchart PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 36 When T8 is enabled, the output T8_OUT switches to the initial value (CTR1, D1). If the initial value (CTR1, D1) is 0, TC8L is loaded; otherwise, TC8H is loaded into the counter. In SINGLE-PASS mode (CTR0, D6), T8 counts down to 0 and stops, T8_OUT toggles, the time-out status bit (CTR0, D5) is set, and a time-out interrupt can be generated if it is enabled (CTR0, D1). In MODULO-N mode, upon reaching terminal count, T8_OUT is toggled, but no interrupt is generated. From that point, T8 loads a new count (if the T8_OUT level now is 0), TC8L is loaded; if it is 1, TC8H is loaded. T8 counts down to 0, toggles T8_OUT, and sets the time-out status bit (CTR0, D5), thereby generating an interrupt if enabled (CTR0, D1). One cycle is thus completed. T8 then loads from TC8H or TC8L according to the T8_OUT level and repeats the cycle, see Figure 18.

The new values take effect when they are loaded. Caution: Note: To ensure known operation do not write these registers at the time the values are to be loaded into the counter/timer. An initial count of 1 is not allowed (a non-function occurs). An initial count of 0 causes TC8 to count from 0 to FFh to FEh. The letter h denotes hexadecimal values. Transition from 0 to FFh is not a timeout condition. PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 37 Caution: Using the same instructions for stopping the counter/timers and setting the status bits is not recommended. Two successive commands are necessary. First, the counter/timers must be stopped. Second, the status bits must be reset. These commands are required because it takes one counter/timer clock interval for the initiated event to actually occur, see Figure 19 and Figure 20.

T8_OUT in MODULO-N Mode T8 DEMODULATION Mode You must program TC8L and TC8H to FFh. After T8 is enabled, when the first edge (rising, falling, or both depending on CTR1, D5; D4) is detected, it starts to count down. When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected during counting, the current value of T8 is complemented and put into one of the capture registers. If it is a positive edge, data is put into LO8; if it is a negative edge, data is put into HI8. From that point, one of the edge detect status bits (CTR1, D1; D0) is set, and an interrupt can be generated if enabled (CTR0, D2). Meanwhile, T8 is loaded with FFh and starts counting again. If T8 reaches 0, the time-out status bit (CTR0, D5) is set, and an PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 38 interrupt can be generated if enabled (CTR0, D1). T8 then continues counting from FFh (see Figure 21 and Figure 22).

DEMODULATION Mode Flowchart PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 40 T16 TRANSMIT Mode In NORMAL or PING-PONG mode, the output of T16 when not enabled, is dependent on CTR1, D0. If it is a 0, T16_OUT is a 1; if it is a 1, T16_OUT is 0. You can force the output of T16 to either a 0 or 1 whether it is enabled or not by programming CTR1 D3; D2 to a 10 or 11. When T16 is enabled, TC16H * 256 + TC16L is loaded, and T16_OUT is switched to its initial value (CTR1, D0). When T16 counts down to 0, T16_OUT is toggled (in NORMAL or PING-PONG mode), an interrupt (CTR2, D1) is generated (if enabled), and a status bit (CTR2, D5) is set, see Figure 23.

If T16 is in SINGLE-PASS mode, it is stopped at this point (see Figure 24). If it is in MODULO-N mode, it is loaded with TC16H * 256 + TC16L, and the counting continues (see Figure 25). You can modify the values in TC16H and TC16L at any time. The new values take effect when they are loaded. PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 41 Caution: Do not load these registers at the time the values are to be loaded into the counter/timer to ensure known operation. An initial count of 1 is not allowed. An initial count of 0 causes T16 to count from 0 to FFFFh to FFFEh. Transition from 0 to FFFFh is not a timeout condition.

T16_OUT in MODULO-N Mode T16 DEMODULATION Mode You must program TC16L and TC16H to FFh. After T16 is enabled, and the first edge (rising, falling, or both depending on CTR1 D5; D4) is detected, T16 captures HI16 and LO16, reloads, and begins counting. If D6 of CTR2 Is 0 When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is detected during counting, the current count in T16 is complemented and put into HI16 and LO16. When data is captured, one of the edge detect status bits (CTR1, D1; D0) is set, and an interrupt is generated if enabled (CTR2, D2). T16 is loaded with FFFFh and starts again. PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 42 This T16 mode is generally used to measure space time, the length of time between bursts of carrier signal (marks). If D6 of CTR2 Is 1 T16 ignores the subsequent edges in the input signal and continues counting down. A timeout of T8 causes T16 to capture its current value and generate an interrupt if enabled (CTR2, D2). In this case, T16 does not reload and continues counting. If the D6 bit of CTR2 is toggled (by writing a 0 then a 1 to it), T16 captures and reloads on the next edge (rising, falling, or both depending on CTR1, D5; D4), continuing to ignore subsequent edges. This T16 mode generally measures mark time, the length of an active carrier signal burst. If T16 reaches 0, T16 continues counting from FFFFh. Meanwhile, a status bit (CTR2 D5) is set, and an interrupt timeout can be generated if enabled (CTR2 D1). PING-PONG Mode This operation mode is only valid in TRANSMIT mode. T8 and T16 must be programmed in SINGLE-PASS mode (CTR0, D6; CTR2, D6), and PING-PONG mode must be programmed in CTR1, D3; D2. You can begin the operation by enabling either T8 or T16 (CTR0, D7 or CTR2, D7). For example, if T8 is enabled, T8_OUT is set to this initial value (CTR1, D1). According to T8_OUT's level, TC8H or TC8L is loaded into T8. After the terminal count is reached, T8 is disabled, and T16 is enabled. T16_OUT then switches to its initial value (CTR1, D0), data from TC16H and TC16L is loaded, and T16 starts to count. After T16 reaches the terminal count, it stops, T8 is enabled again, repeating the entire cycle. Interrupts can be allowed when T8 or T16 reaches terminal control (CTR0, D1; CTR2, D1). To stop the Ping-Pong operation, write 00 to bits D3 and D2 of CTR1, see Figure 26. Note: Enabling Ping-Pong operation while the counter/timers are running might cause intermittent counter/timer function. Disable the counter/timers and reset the status Flags before instituting this operation. Enable TC8 Timeout Enable Ping-Pong CTR1 TC16 Timeout Figure 26. PING-PONG Mode Diagram PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 43 Initiating PING-PONG Mode First, make sure both counter/timers are not running. Set T8 into SINGLE-PASS mode (CTR0, D6), set T16 into SINGLE-PASS mode (CTR2, D6), and set the PING-PONG mode (CTR1, D2; D3). These instructions can be in random order. Finally, start PINGPONG mode by enabling either T8 (CTR0, D7) or T16 (CTR2, D7), see Figure 26.

Output Circuit The initial value of T8 or T16 must not be 1. If you stop the timer and restart the timer, reload the initial value to avoid an unknown previous value. During PING-PONG Mode The enable bits of T8 and T16 (CTR0, D7; CTR2, D7) are set and cleared alternately by hardware. The timeout bits (CTR0, D5; CTR2, D5) are set every time the counter/timers reach the terminal count. Timer Output The output logic for the timers is displayed in Figure 27. P34 is used to output T8-OUT when D0 of CTR0 is set. P35 is used to output the value of TI6-OUT when D0 of CTR2 is set. When D6 of CTR1 is set, P36 outputs the logic combination of T8-OUT and T16OUT determined by D5 and D4 of CTR1. Interrupts The Crimzon ZLP32300 features six different interrupts (see Table 11 on page 45). The interrupts are maskable and prioritized (see Figure 28). The six sources are divided as follows: three sources are claimed by Port 3 lines P33-P31, two by the PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 44 counter/timers (see Table 11 on page 45) and one for low-voltage detection. The Interrupt Mask Register (globally or individually) enables or disables the six interrupt requests. The source for IRQ is determined by bit 1 of the Port 3 mode register (P3M). When in DIGITAL mode, Pin P33 is the source. When in ANALOG mode, the output of the Stop Mode Recovery source logic is used as the source for the interrupt, see Figure 33 on page 52. P33 Stop Mode Recovery Source 0 P31 IRQ Register D6, D7 D1 of P3M Register P32 Interrupt Edge Select IRQ2 1 IRQ0 Timer 16 IRQ1 IRQ3 Timer 8 IRQ4 Low-Voltage Detection IRQ5 IRQ IMR 5 IPR Global Interrupt Enable Interrupt Request Priority Logic Vector Select Figure 28.

An interrupt machine cycle activates when an interrupt request is granted. As a result, all subsequent interrupts are disabled, and the Program Counter and Status Flags are saved. The cycle then branches to the program memory vector location reserved for that interrupt. All Crimzon ZLP32300 interrupts are vectored through locations in the program memory. This memory location and the next byte contain the 16-bit address of the interrupt service routine for that particular interrupt request. To accommodate polled interrupt systems, interrupt inputs are masked, and the Interrupt Request register is polled to determine which of the interrupt requests require service. An interrupt resulting from AN1 is mapped into IRQ2, and an interrupt from AN2 is mapped into IRQ0. Interrupts IRQ2 and IRQ0 can be rising, falling, or both edge triggered. These interrupts are programmable. The software can poll to identify the state of the pin. Programming bits for the Interrupt Edge Select are located in the IRQ Register (R250), bits D7 and D6. The configuration is indicated in Table 12. Table 12.

The crystal must be AT cut, 1 MHz to 8 MHz maximum, with a series resistance (RS) less than or equal to 100 . The on-chip oscillator can be driven with a suitable external clock source. The crystal must be connected across XTAL1 and XTAL2 using the recommended capacitors from each pin to ground. The typical capacitor value is 10 pF for 8 MHz. Also check with the crystal supplier for the optimum capacitance. XTAL1 XTAL1 XTAL1 XTAL2 XTAL2 XTAL2 C1 C2 Crystal C1, C2 = 10 pF * f = 8 MHz External Clock Ceramic Resonator f = 8 MHz *Note: preliminary value. Figure 29. Oscillator Configuration Zilog's IR MCU supports crystal, resonator, and oscillator. Most resonators have a frequency tolerance of less than 0.5%, which is enough for remote control application. Resonator has a very fast startup time, which is around few hundred microseconds. Most crystals have a frequency tolerance of less than 50 ppm (0.005%). However, crystal needs longer startup time than the resonator. The large loading capacitance slows down the oscillation startup time. Zilog(R) suggests not to use more than 10 pF loading capacitor for the crystal. If the stray capacitance of the PCB or the crystal is high, the loading capacitance C1 and C2 must be reduced further to ensure stable oscillation before the TPOR (Power-On Reset time is typically 5-6 ms, see Table 20 on page 79). For Stop Mode Recovery operation, bit 5 of SMR register allows you to select the Stop Mode Recovery delay, which is the TPOR. If Stop Mode Recovery delay is not selected, the MCU executes instruction immediately after it wakes up from the STOP mode. If resonator or crystal is used as a clock source then Stop Mode Recovery delay needs to be selected (bit 5 of SMR = 1). PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 47 For both resonator and crystal oscillator, the oscillation ground must go directly to the ground pin of the microcontroller. The oscillation ground must use the shortest distance from the microcontroller ground pin and it must be isolated from other connections. Power Management Power-On Reset A timer circuit clocked by a dedicated on-board RC-oscillator is used for the Power-On Reset timer function. The POR time allows VDD and the oscillator circuit to stabilize before instruction execution begins. The POR timer circuit is a one-shot timer triggered by one of three conditions: * * * Power Fail to Power OK status, including Waking up from VBO Standby Stop Mode Recovery (if D5 of SMR = 1) WDT Timeout The POR timer is 2.5 ms minimum. Bit 5 of the Stop Mode Register determines whether the POR timer is bypassed after Stop Mode Recovery (typical for external clock). HALT Mode This instruction turns off the internal CPU clock, but not the XTAL oscillation. The counter/timers and external interrupts IRQ0, IRQ1, IRQ2, IRQ3, IRQ4, and IRQ5 remain active. The devices are recovered by interrupts, either externally or internally generated. An interrupt request must be executed (enabled) to exit HALT Mode. After the interrupt service routine, the program continues from the instruction after HALT Mode. STOP Mode This instruction turns OFF the internal clock and external crystal oscillation, reducing the standby current to 10 A or less. STOP mode is terminated only by a reset, such as WDT time-out, POR or SMR. This condition causes the processor to restart the application program at address 000Ch. To enter STOP (or HALT) mode, first flush the instruction pipeline to avoid suspending execution in mid-instruction. Execute a NOP (Opcode = FFh) immediately before the appropriate sleep instruction, as follows: FF 6F NOP STOP ; clear the pipeline ; enter Stop Mode FF 7F NOP HALT ; clear the pipeline ; enter HALT Mode or PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 48 Port Configuration Port Configuration Register The Port Configuration (PCON) register (see Figure 30) configures the comparator output on Port 3.

A 1 in this location sets the output to push-pull, and a 0 sets the output to open-drain. Port 0 Output Mode (D2) Bit 2 controls the output mode of Port 0.

PS020823-0208 Functional Description Crimzon(R) ZLP32300 Product Specification 49 Stop Mode Recovery Stop Mode Recovery Register (SMR) This register selects the clock divide value and determines the mode of Stop Mode Recovery (see Figure 31). All bits are write only except bit 7, which is read only. Bit 7 is a Flag bit that is hardware set on the condition of Stop recovery and reset by a power-on cycle. Bit 6 controls whether a low level or a high level at the XOR-gate input (see Figure 33 on page 52) is required from the recovery source. Bit 5 controls the reset delay after recovery. Bits D2, D3, and D4 of the SMR register specify the source of the Stop Mode Recovery signal. Bits D0 determines if SCLK/TCLK are divided by 16 or not.

For example, if the NOR of P23-P20 is selected as the recovery source and P20 is configured as an output, the remaining SMR pins (P23-P21) form the NOR equation. This condition allows the remaining inputs to control the AND/OR function, refer to SMR2 register on page 54 for other recover sources. Stop Mode Recovery Delay Select (D5) This bit, if low, disables the TPOR delay after Stop Mode Recovery. The default configuration of this bit is 1. If the `fast' wake up is selected, the Stop Mode Recovery source must be kept active for at least 10 TpC. Note: This bit must be set to 1 if a crystal or resonator clock source is used. The TPOR delay allows the clock source to stabilize before executing instructions. Stop Mode Recovery Edge Select (D6) A 1 in this bit position indicates that a High level on any one of the recovery sources wakes the Crimzon ZLP32300 from STOP mode. A 0 indicates Low level recovery. The default is 0 on POR. Cold or Warm Start (D7) This bit is read only. It is set to 1 when the device is recovered from STOP mode. The bit is set to 0 when the device reset is other than Stop Mode Recovery.

Functional Description Crimzon(R) ZLP32300 Product Specification 55 Watchdog Timer Mode Watchdog Timer Mode Register (WDTMR) The Watchdog Timer is a retriggerable one-shot timer that resets the Z8(R) if it reaches its terminal count. The WDT must initially be enabled by executing the WDT instruction. On subsequent executions of the WDT instruction, the WDT is refreshed. The WDT circuit is driven by an on-board RC-oscillator. The WDT instruction affects the Zero (Z), Sign (S), and Overflow (V) Flags. The POR clock source the internal RC-oscillator. Bits 0 and 1 of the WDT register control a tap circuit that determines the minimum time-out period. Bit 2 determines whether the WDT is active during HALT, and Bit 3 determines WDT activity during Stop. Bits 4 through 7 are reserved (see Figure 35). This register is accessible only during the first 60 processor cycles (120 XTAL clocks) from the execution of the first instruction after Power-on reset, Watchdog Reset, or a Stop Mode Recovery (see Figure 34). After this point, the register cannot be modified by any means (intentional or otherwise). The WDTMR cannot be read. The register is located in Bank F of the Expanded Register Group at address location 0Fh. It is organized as shown in Figure 35.

Reset is globally driven when VDD falls below VBO. A small drop in VDD causes the XTAL1 and XTAL2 circuitry to stop the crystal or resonator clock. If the VDD is allowed to stay above VRAM, the RAM content is preserved. When the power level is returned to above VBO, the device performs a POR and functions normally.

Functional Description Crimzon(R) ZLP32300 Product Specification 59 Voltage Detection and Flags The Voltage Detection register (LVD, register 0Ch at the expanded register bank 0Dh) offers an option of monitoring the VCC voltage. The Voltage Detection is enabled when bit 0 of LVD register is set. Once Voltage Detection is enabled, the VCC level is monitored in real time. The HVD Flag (bit 2 of the LVD register) is set only if VCC is higher than VHVD. The LVD Flag (bit 1 of the LVD register) is set only if VCC is lower than the VLVD. When Voltage Detection is enabled, the LVD Flag also triggers IRQ5. The IRQ bit 5 latches the low-voltage condition until it is cleared by instructions or reset. The IRQ5 interrupt is served if it is enabled in the IMR register. Otherwise, bit 5 of IRQ register is latched as a Flag only. Note: PS020823-0208 If it is necessary to receive an LVD interrupt upon power-up at an operating voltage lower than the low battery detect threshold, enable interrupts using the Enable Interrupt (EI) instruction prior to enabling the voltage detection.
