Doc ID 7838 Rev 2
PD2
1
I/O
CMOS
or
Open
Drain
PD2 pin of Port D. This port pin can be configured to have the following functions:
1. MCU I/O - standard output or input port.
2. Transparent PLD input (can also be PLD input for address A16 and above).
3. PSD Chip Select input (CSI). When low, the MCU can access the PSD memory
and I/O. When high, the PSD memory blocks are disabled to conserve power. The
falling edge of this signal can be used to get the device out of Power-down mode.
PD3
2
I/O
CMOS
or
Open
Drain
PD3 pin of Port D. This port pin can be configured to have the following functions:
1. MCU I/O - standard output or input port.
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.
PE0
71
I/O
CMOS
or
Open
Drain

3. TMS input for the JTAG Serial Interface.
PE1
72
I/O
CMOS
or
Open
Drain
PE1 pin of Port E. This port pin can be configured to have the following functions:
1. MCU I/O - standard output or input port.

4. Ready/Busy output for parallel in-system programming (ISP).
PE5
76
I/O
CMOS
or
Open
Drain
PE5 pin of Port E. This port pin can be configured to have the following functions:
1. MCU I/O - standard output or input port.
2. Latched address output.
3. TERR active low output for the JTAG Serial Interface.
