The integrated CAN 2.0 networking protocol provides for efficient communication to a high-speed CAN bus. The serial debug unit (SDU) provides system debug and development capabilities. The SDU can set a single hardware breakpoint. In addition, the SDU provides read and write access to code RAM through a high-speed, dedicated serial link. A stack overflow/underflow monitor assists in code development by causing a nonmaskable interrupt if the stack pointer crosses a user-defined boundary. The 16-channel A/D converter supports an auto-scan mode that operates with no CPU overhead. Each A/D channel has a dedicated result register. The EPA supports high-speed event captures and output compares with 15 programmable, high-speed channels. Datasheet 7 Intel(R) 88CO196EC 1.1 Nomenclature Overview Figure 2.

Signal Descriptions (Sheet 1 of 9) Name Type Description System Address Bus A15:0 O These address pins provide address bits 0-15 during the entire external memory cycle during both multiplexed and demultiplexed bus modes. Address Pins 16-20 A20:16 O These address pins provide address bits 16-20 during the entire external memory cycle during both multiplexed and demultiplexed bus modes, supporting extended addressing of the 2-Mbyte address space. NOTE: Internally, there are 24 address bits; however, only 21 external address pins (A20:0) are implemented. The internal address space is 16 Mbytes (000000-FFFFFFH) and the external address space is 2 Mbytes (000000-1FFFFFH). The microcontroller resets to FF2080H in internal memory or 1F2080H in external memory. A20:16 share package pins with P6.4:0 and PBUS20:16. Analog Channels ACH15:0 I These signals are analog inputs to the A/D converter. The ANGND and VREF pins must be connected for the A/D converter to function. Address/Data Lines The function of these pins depends on the bus width and mode. 16-bit Multiplexed Bus Mode: AD15:0 drive address bits 0-15 during the first half of the bus cycle and drive or receive data during the second half of the bus cycle. 8-bit Multiplexed Bus Mode: AD15:0 I/O AD15:8 drive address bits 8-15 during the entire bus cycle. AD7:0 drive address bits 0-7 during the first half of the bus cycle and drive or receive data during the second half of the bus cycle. 16-bit Demultiplexed Mode: AD15:0 drive or receive data during the entire bus cycle. 8-bit Demultiplexed Mode: AD7:0 drive or receive data during the entire bus cycle. AD15:8 drive the data that is currently on the high byte of the internal bus. AD15:8 share package pins with P4.7:0. AD7:0 share package pins with P3.7:0. Address Valid ADV# O This active-low output signal is asserted only during external memory accesses. ADV# indicates that valid address information is available on the system address/data bus. The signal remains low while a valid bus cycle is in progress and is returned high as soon as the bus cycle completes. An external latch can use this signal to demultiplex the address from the address/data bus. A decoder can also use this signal to generate chip selects for external memory. ADV# shares a package pin with P5.0 and ALE. Auto Increment AINC# I During slave programming, this active-low input enables the auto-increment feature. (Auto increment allows reading or writing of sequential flash memory locations, without requiring address transactions across the programming bus for each read or write.) AINC# is sampled after each location is programmed or dumped. If AINC# is asserted, the address is incremented and the next data word is programmed or dumped. AINC# shares a package pin with P2.4. Datasheet 11 Intel(R) 88CO196EC Table 3. Signal Descriptions (Sheet 2 of 9) Name Type Description Address Latch Enable ALE O This active-high output signal is asserted only during external memory cycles. ALE signals the start of an external bus cycle and indicates that valid address information is available on the system address/data bus. An external latch can use this signal to demultiplex address bits 0-15 from the address/data bus in multiplexed mode. ALE shares a package pin with P5.0 and ADV#. Analog Ground ANGND GND ANGND must be connected for A/D converter operation. ANGND and VSS should be nominally at the same potential. Byte High Enable During 16-bit bus cycles, this active-low output signal is asserted for word and high-byte reads and writes to external memory. BHE# indicates that valid data is being transferred over the upper half of the system data bus. Use BHE#, in conjunction with address bit 0 (A0 for a demultiplexed address bus, AD0 for a multiplexed address/data bus), to determine which memory byte is being transferred over the system bus: BHE# O BHE# AD0 or A0 Byte(s) Accessed 0 0 1 0 1 0 both bytes high byte only low byte only BHE# shares a package pin with P5.5, TMODE1# and WRH#. When this pin is configured as a special-function signal (P5_MODE.5 = 1), the chip configuration register 0 (CCR0) determines whether it functions as BHE# or WRH#. CCR0.2 = 1 selects BHE#; CCR0.2 = 0 selects WRH#. Block x Active. When active, these signals indicate that programming of data is occurring within the corresponding flash memory address range or that the corresponding physical block is being erased. The address range and physical block associated with the BLKx# signals are as follows: BLK3:0# O BLK0# BLK1# BLK2# BLK3# Address Range FC0000-FCFFFFH FD0000-FDFFFFH FE0000-FEFFFFH FF0000-FFFFFFH Physical Block even bytes at FC0000-FDFFFEH odd bytes at FC0001-FDFFFFH even bytes at FE0000-FFFFFEH odd bytes at FE0001-FFFFFFH During test-ROM execution mode, the contents of pages FFH and FBH are swapped. BLK1:0# shares a package pin with P8.1:0 and EPAPWM9:8. BLK2# shares a package pin with P8.2, EPA10, and T1CLK. BLK3# shares a package pin with P8.3, EPA11, and T1RST. Bus Request BREQ# O This active-low output signal is asserted during a hold cycle when the bus controller has a pending external memory cycle. When the bus-hold protocol is enabled (WSR.7 is set), the P5.4/BREQ# pin can function only as BREQ#, regardless of the configuration selected through the port configuration registers (P5_MODE, P5_DIR, and P5_REG). An attempt to change the pin configuration is ignored until the bus-hold protocol is disabled (WSR.7 is cleared). The microcontroller can assert BREQ# at the same time as or after it asserts HLDA#. Once it is asserted, BREQ# remains asserted until HOLD# is deasserted. BREQ# shares a package pin with P5.4 and TMODE0#. Clock Output CLKOUT O Output of the internal clock generator. You can select one of four frequencies: f/2, f/4, f/8, or f/16. CLKOUT has a 50% duty cycle. CLKOUT shares a package pin with P2.7 and PACT#. 12 Datasheet Intel(R) 88CO196EC Table 3. Signal Descriptions (Sheet 3 of 9) Name Type Description Cumulative Program Verification CPVER O During slave or UPROM programming, a high signal indicates that the program operation was successful, while a low signal indicates that an error occurred during the program operation. CPVER shares a package pin with P2.6, HLDA#, and ONCE#. Code RAM Busy CRBUSY# O CRDCLK I When active, this signal indicates that the serial debug unit (SDU) is busy processing a code RAM command. No data can be transferred during this time. Code RAM Clock Provides the clock signal for the serial debug unit (SDU). The maximum clock frequency equals one-half the operating frequency (f/2). Code RAM Data Input CRIN I Serial input for test instructions and data into the serial debug unit (SDU). Data is transferred in 8-bit bytes with the most-significant bit (MSB) first. Each byte is sampled on the rising edge of CRDCLK. Code RAM Data Output CROUT O Serial output for data from the serial debug unit (SDU). Data is transferred in 8-bit bytes with the most-significant bit (MSB) first. Each byte is valid on the rising edge of CRDCLK. Chip-select Lines 0-2 CS2:0# O The active-low output CSx# is asserted during an external memory cycle when the address to be accessed is in the range programmed for chip select x. If the external memory address is outside the range assigned to the three chip selects, no chip-select output is asserted and the bus configuration defaults to the CS2# values. Immediately following reset, CS0# is automatically assigned to the range (1F2000-1F20FFH if external). CS2:0# share package pins with P6.7:5 and PMODE2:0. External Access EA# I This input determines whether memory accesses to flash program memory partitions (FC0000-FFFFFFH) are directed to internal or external memory. These accesses are directed to internal flash memory if EA# is held high and to external memory if EA# is held low. For an access to any other memory location, the value of EA# is irrelevant. EA# is sampled and latched only on the rising edge of RESET#. Changing the level of EA# after reset has no effect. Always connect EA# to VSS when using a microcontroller that has no internal nonvolatile memory or V CC when using the internal flash memory. Event Processor Array (EPA) Capture/Compare Channels EPA14:10 I/O High-speed input/output signals for the EPA capture/compare channels. EPA14:10 share package pins with the following signals: EPA10/P8.2/T1CLK/BLK2#, EPA11/P8.3/T1RST/BLK3#, EPA12/P8.4/T2CLK, EPA13/P8.5/T2RST, EPA14/P8.6. Event Processor Array (EPA) PWM Receiver/Transmitter Channels EPAPWM9:0 I/O High-speed input/output signals for the enhanced EPA PWM receiver/transmitter channels. EPAPWM9:8 share package pins with P8.1:0 and BLK1:0#. EPAPWM7:0 share package pins with P7.7:0. Datasheet 13 Intel(R) 88CO196EC Table 3. Signal Descriptions (Sheet 4 of 9) Name Type Description External Interrupt In normal operating mode, a rising edge on EXTINT sets the EXTINT interrupt pending bit. EXTINT is sampled during phase 2 (CLKOUT high). The minimum high time is one state time. EXTINT I In powerdown mode, asserting the EXTINT signal for at least 50 ns causes the device to resume normal operation. The interrupt does not need to be enabled, but the pin must be configured as a special-function input. If the EXTINT interrupt is enabled, the CPU executes the interrupt service routine. Otherwise, the CPU executes the instruction that immediately follows the command that invoked the power-saving mode. In idle mode, asserting any enabled interrupt causes the device to resume normal operation. EXTINT shares a package pin with P2.2 and PROG#. Bus Hold Acknowledge HLDA# O The HLDA# pin is used in systems with more than one processor using the system bus. The microcontroller asserts HLDA# to indicate that it has released the bus in response to HOLD# and another processor can take control. (This signal is active low to avoid misinterpretation by external hardware immediately after reset.) When the bus-hold protocol is enabled (WSR.7 is set), the P2.6/HLDA# pin can function only as HLDA#, regardless of the configuration selected through the port configuration registers (P2_MODE, P2_DIR, and P2_REG). An attempt to change the pin configuration is ignored until the bus-hold protocol is disabled (WSR.7 is cleared). Bus Hold Request An external device uses this active-low input signal to request control of the bus. HOLD# I When the bus-hold protocol is enabled (WSR.7 is set), the P2.5/HOLD# pin can function only as HOLD#, regardless of the configuration selected through the port configuration registers (P2_MODE, P2_DIR, and P2_REG). An attempt to change the pin configuration is ignored until the bus-hold protocol is disabled (WSR.7 is cleared). If P2.5 is configured as a general-purpose I/O signal, the device does not recognize signals on this pin as HOLD#. Instead, the bus controller receives an internal HOLD signal. This enables the device to access the external bus while it is performing I/O at P2.5. Instruction Fetch INST O When high, INST indicates that an instruction is being fetched from external memory. The signal remains high during the entire bus cycle of an external instruction fetch. INST is low for data accesses, including interrupt vector fetches and chip configuration byte reads. INST is low during internal memory fetches. INST shares a package pin with P5.1. Nonmaskable Interrupt NMI I In normal operating mode, a rising edge on NMI generates a nonmaskable interrupt. NMI has the highest priority of all prioritized interrupts. Assert NMI for greater than one state time to guarantee that it is recognized. On-circuit Emulation ONCE# I Holding ONCE# low during the rising edge of RESET# places the microcontroller into on-circuit emulation (ONCE) mode. This mode puts all pins into a high-impedance state, thereby isolating the microcontroller from other components in the system. The value of ONCE# is latched when the RESET# pin goes inactive. While the microcontroller is in ONCE mode, you can debug the system using a clip-on emulator. To exit ONCE mode, reset the microcontroller by pulling the RESET# signal low. To prevent inadvertent entry into ONCE mode, either configure this pin as an output or hold it high during reset and ensure that your system meets the VIH specification. ONCE# shares a package pin with P2.6, TMODE1#, and CPVER. 14 Datasheet Intel(R) 88CO196EC Table 3.

Port 5 shares package pins with the following signals: P5.0/ALE/ADV#, P5.1/INST, P5.2/WR#/WRL#, P5.3/RD#, P5.4/BREQ#/TMODE0#, P5.5/BHE#/WRH#, P5.6/READY, and P5.7/RPD.

O Programming Active During slave or UPROM programming, a low signal indicates that programming is in progress, while a high signal indicates that the operation is complete. PACT# PACT# shares a package pin with P2.7 and CLKOUT. Programming ALE PALE# I During slave or UPROM programming, a falling edge causes the microcontroller to read the programming bus. PALE# is multiplexed with P2.1 and RXD. Address/Command/Data Bus PBUS20:0 I/O Address and data input/output bus during slave and UPROM programming. PBUS20:16 share package pins with A20:16 and P6.4:0; PBUS15:8 share package pins with AD15:8 and P4.7:0; PBUS7:0 share package pins with AD7:0 and P3.7:0. Phase-locked Loop Enable PLLEN I This active-high input pin enables the on-chip clock multiplier. This pin should be tied to VCC to activate the PLL or V SS to disable the PLL. The state of the PLL can only be changed at the time of reset. Programming Mode Select PMODE2:0 I These pins, along with the TMODE1:0# pins, determine the programming mode. PMODE2:0 are sampled after a device reset and must be static while the microcontroller is operating. PMODE2:0 share package pins with P6.7:5 and CS2:0#. Programming Start PROG# I During programming, a falling edge latches data on the programming bus and begins programming, while a rising edge ends programming. The current location is programmed with the same data as long as PROG# remains asserted, so the data on the programming bus must remain stable while PROG# is active. During a word dump, a falling edge causes the contents of a flash memory location to be output on the PBUS, while a rising edge ends the data transfer. PROG# shares a package pin with P2.2 and EXTINT. Read RD# O Read-signal output to external memory. RD# is asserted only during external memory reads. RD# shares a package pin with P5.3. Ready Input READY I This active-high input can be used to insert wait states in addition to those programmed in the chip configuration byte 0 (CCB0) and the bus control x register (BUSCONx). CCB0 is programmed with the minimum number of wait states (0-3) for an external fetch of CCB1, and BUSCONx is programmed with the minimum number of wait states (0-3) for all external accesses to the address range assigned to the chip-select x channel. If READY is low when the programmed number of wait states is reached, additional wait states are added until READY is pulled high. READY shares a package pin with P5.6. 16 Datasheet Intel(R) 88CO196EC Table 3. Signal Descriptions (Sheet 7 of 9) Name Type Description Reset RESET# I/O A level-sensitive reset input to, and an open-drain system reset output from, the microcontroller. Either a falling edge on RESET# or an internal reset turns on a pull-down transistor connected to the RESET# pin for 16 state times. In the powerdown and idle modes, asserting RESET# causes the microcontroller to reset and return to normal operating mode. After a reset, the first instruction fetch is from FF2080H (or 1F2080H in external memory). Return from Powerdown Timing pin for the return-from-powerdown circuit. If your application uses powerdown mode, connect a capacitor between RPD and VSS if either of the following conditions are true. * The internal oscillator is the clock source * The phase-locked loop (PLL) circuitry is enabled (see PLLEN signal description) RPD I The capacitor causes a delay that enables the oscillator and PLL circuitry to stabilize before the internal CPU and peripheral clocks are enabled. Refer to the "Special Operating Modes" chapter of the for details on selecting the capacitor. The capacitor is not required if your application uses powerdown mode and if both of the following conditions are true. * An external clock input is the clock source * The phase-locked loop circuitry is disabled If your application does not use powerdown mode, leave this pin unconnected. RPD shares a package pin with P5.7. Receive CAN Message RXCAN I This signal carries messages from other nodes on the CAN bus to the integrated CAN controller. Receive Serial Data RXD I/O In modes 1, 2, and 3, RXD receives serial port input data. In mode 0, it functions as either an input or an open-drain output for data. RXD shares a package pin with P2.1 and PALE#. Clock Pins for SSIO0 and 1 SC1:0 I/O In standard mode, SC0 is the serial clock pin for channel 0 and SC1 is the serial clock pin for channel 1. In duplex and channel-select modes, SC0 is the serial clock pin for both channels 0 and 1 and SC1 is not available. SC0 shares a package pin with P9.2, and SC1 shares a package pin with P9.4. Data Pins for SSIO0 and 1 SD1:0 I/O These pins are the data I/O pins for SSIO0 and 1. For transmissions, configure SDx as a complementary output signal. For receptions, configure SDx as a high-impedance input signal. SD0 shares a package pin with P9.3, and SD1 shares a package pin with P9.5. Timer 1 External Clock T1CLK I External clock for timer 1. Timer 1 is programmable to increment or decrement on the rising edge, the falling edge, or both rising and falling edges of T1CLK. T1CLK shares a package pin with P8.2, EPA10, and BLK2#. Timer 2 External Clock T2CLK I External clock for timer 2. Timer 2 is programmable to increment or decrement on the rising edge, the falling edge, or both rising and falling edges of T2CLK. and External clock for the serial I/O baud-rate generator input (program selectable). T2CLK shares a package pin with P8.4 and EPA12. Datasheet 17 Intel(R) 88CO196EC Table 3. Signal Descriptions (Sheet 8 of 9) Name Type Description Timer 1 External Reset T1RST I External reset for timer 1. Timer 1 is programmable to reset on the rising edge, the falling edge, or both rising and falling edges of T1RST. T1RST shares a package pin with P8.3, EPA11, and BLK3#. Timer 2 External Reset T2RST I External reset for timer 2. Timer 2 is programmable to reset on the rising edge, the falling edge, or both rising and falling edges of T2RST. T2RST shares a package pin with P8.5 and EPA13. TMODE1:0# Test-Mode Entry I If these pins are held low during reset, the microcontroller will enter a test mode. The value of several other pins defines the actual test mode. All test modes, except TROM execution, are reserved for Intel factory use. If you choose to configure these signals as inputs, always hold them high during reset and ensure that your system meets the VIH specification to prevent inadvertent entry into test mode. TMODE0# shares a package pin with P5.4 and BREQ#; TMODE1# shares a package pin with P5.5, BHE#, WRH#. Transmit CAN Message TXCAN O This signal carries messages from the integrated CAN controller to other nodes on the CAN bus. Transmit Serial Data TXD O In serial I/O modes 1, 2, and 3, TXD transmits serial port output data. In mode 0, it is the serial clock output. TXD shares a package pin with P2.0.

The sample time is the length of time that the analog input voltage is actually connected to the sample capacitor. If this time is too short, the sample capacitor will not charge completely. If the sample time is too long, the input voltage may change and cause conversion errors. The conversion time is the length of time required to convert the analog input voltage stored on the sample capacitor to a digital value. The conversion time must be long enough for the comparator and circuitry to settle and resolve the voltage. Excessively long conversion times allow the sample capacitor to discharge, degrading accuracy. The AD_TIME register programs the A/D sample and conversion times. Use the TSAM and TCONV specifications in Table 12 and Table 14 to determine appropriate values for SAM and CONV; otherwise, erroneous conversion results may occur. When the SAM and CONV values are known, write them to the AD_TIME register. Do not write to this register while a conversion is in progress; the results are unpredictable. Use the following formulas to determine the SAM and CONV values. TS A M x f - 2 SAM = ------------------------------8 xf-3 T CONV CONV = ---------------------------------- - 1 2xB where: SAM 38 equals a number, 1 to 7, to be written to the AD_TIME register CONV equals a number, 2 to 31, to be written to the AD_TIME register TSAM is the sample time, in sec (Table 12 and Table 14) TCONV is the conversion time, in sec (Table 12 and Table 14) f is the operating frequency, in MHz B is the number of bits to be converted (8 or 10) Datasheet Intel(R) 88CO196EC 6.7.1 AC Characteristics -- A/D Converter, 10-Bit Mode Table 12. 10-bit A/D Operating Conditions Symbol Description Min Max Units - 40 + 125 C V Notes 1 TC Case Temperature VCC Digital Supply Voltage 4.75 5.25 VREF Analog Supply Voltage 4.75 5.25 TSAM Sample Time TCONV Conversion Time 1.0 10.0 15.0 V 2 s 3 s 3 NOTES: 1.
