Description
PC7
11
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
10
I/O
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
9
I/O
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
8
I/O
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.
