Initial value

R/W

PCPCR is an 8-bit readable/writable register that controls the MOS input pull-up function

incorporated into port C on an individual bit basis.

When a PCDDR bit is cleared to 0 (input port setting) in mode 2, 3, 6, or 7, setting the

corresponding PCPCR bit to 1 turns on the MOS input pull-up for the corresponding pin.

PCPCR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its

prior state after a manual reset, and in software standby mode.

Pin Functions

Modes 1, 4, and 5

In modes 1, 4, and 5, port C pins are automatically designated as address outputs.

Port C pin functions in modes 1, 4, and 5 are shown in figure 8.15.
