PC7 pin of Port C. This port pin can be configured to have the following functions:
MCU I/O – write to or read from a standard output or input port.
CPLD macrocell (McellBC7) output.
Input to the PLDs.
DBE – active Low Data Byte Enable input from 68HC912 type MCUs.
This pin can be configured as a CMOS or Open Drain output.
PD0 pin of Port D. This port pin can be configured to have the following functions:
ALE/AS input latches address output from the MCU.
MCU I/O – write or read from a standard output or input port.
Input to the PLDs.
CPLD output (External Chip Select).
PD1 pin of Port D. This port pin can be configured to have the following functions:
MCU I/O – write to or read from a standard output or input port.
Input to the PLDs.
CPLD output (External Chip Select).
CLKIN – clock input to the CPLD macrocells, the APD Unit’s Power-down counter, and
the CPLD AND Array.
PD2 pin of Port D. This port pin can be configured to have the following functions:
MCU I/O - write to or read from a standard output or input port.
Input to the PLDs.
CPLD output (External Chip Select).
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.
