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.
9.10.3 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 9-16.
