Note: 1. The pin numbers in this table are for the PLCC package only. See the package information, on page 83 onwards, for pin numbers
on other package types.
2. These functions can be multiplexed with other functions.
PSD REGISTER DESCRIPTION AND ADDRESS OFFSET
Table 6 shows the offset addresses to the PSD
registers relative to the CSIOP base address. The
CSIOP spaceis the 256bytes of address that is al-
located by the user to the internal PSD registers.
Table 6 provides brief descriptions of the registers
in CSIOP space. The following section gives a
more detailed description.
PC5
13
I/O
PC5 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 macrocell (McellBC5) output.
3. Input to the PLDs.
4. TDI input

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 macrocells, the APD 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.
