I
Active low input. Resets I/O Ports PLD Micro
Cells, some of
the configuration registers and JTAG registers. Must be active
at power up. Reset also aborts the Flash programming/erase
cycle that is in progress.
Port A, PA0-7. This port is pin configurable and has multiple
functions:
1. MCU I/O — standard output or input port
2. CPLD Micro
Cell (McellA0-7) output.
3. Latched, transparent or registered PLD inputs (can also be
PLD input for address A16 and above).
Port B, PB0-7. This port is pin configurable and has multiple
functions:
1. MCU I/O — standard output or input port.
2. CPLD Micro
Cell (McellB0-7 output.
3. Latched, transparent or registered PLD inputs (can also be
PLD input for address A16 and above).
Port C, PC0-7. This port is pin configurable and has multiple
functions:
1. MCU I/O — standard output or input port.
2. External chip select (ECS0-7) output.
3. Latched, transparent or registered PLD inputs (can also be
PLD input for address A16 and above).
Port D pin PD0 can be configured as:
1. ALE or AS input — latches addresses on ADIO0-15 pins
2. AS input — latches addresses on ADIO0-15 pins on the
rising edge.
3. MCU I/O
4. Transparent PLD input (can also be PLD input for address
A16 and above).
Port D pin PD1 can be configured as:
1. MCU I/O
2. Transparent PLD input (can also be PLD input for address
A16 and above).
3. CLKIN clock input — clock input to the CPLD
Micro
Cells, the APD power down counter and CPLD
AND Array.
Port D pin PD2 can be configured as:
1. MCU I/O
2. Transparent PLD input (can also be PLD input for address
A16 and above).
3. CSI input — chip select input. When low, the CSI enables
the internal PSD memories and I/O. When high, the
internal memories are disabled to conserve power. CSI
trailing edge can get the part out of power-down mode.
Port D pin PD3 can be configured as:
1. MCU I/O
2. Transparent PLD input (can also be PLD input for address
A16 and above).
3. WRH — for 16-bit data bus, write to high byte, active low.
Port E, PE0. This port is pin configurable and has multiple
functions:
1. MCU I/O — standard output or input port.
2. Latched address output.
3. TMS input for JTAG-ISP interface.
