Description
PC7

I/O
PC7 pin of Port C. This port pin can be configured to have
the following functions:
1. MCU I/O — write to or read from a standard output or
input port.
2. CPLD Micro
Cell (McellBC7) output.
3. Input to the PLDs.
4. 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:
1. ALE/AS input latches address output from the MCU.
2. MCU I/O — write or read from a standard output or input
port.
3. Input to the PLDs.
4. CPLD output (external chip select).
PD1 pin of Port D. This port pin can be configured to have
the following functions:
1. MCU I/O — write to or read from a standard output or
input port.
2. Input to the PLDs.
3. CPLD output (external chip select).
4. CLKIN — clock input to the CPLD Micro
Cells, the
automatic power-down 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:
1. MCU I/O — write to or read from a standard output or
input port.
2. Input to the PLDs.
3. CPLD output (external chip select).
4. CSI — chip select input. When low, the MCU can access
the PSD memory and I/O. When high, the PSD memory
blocks are disabled to conserve power.
