Section 8 I/O Ports
Port B MOS Pull-Up Control Register (PBPCR)
PBPCR is an 8-bit readable/writable register that controls the MOS input pull-up function
incorporated into port B on an individual bit basis.
When PBDDR bits are cleared to 0 (input port setting) in mode 6 or 7, setting the corresponding
PBPCR bits to 1 turns on the MOS input pull-up for the corresponding pins.
PBPCR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
8.7.3
Modes 4 and 5: In modes 4 and 5, port B pins are automatically designated as address outputs.
Port B pin functions in modes 4 and 5 are shown in figure 8.10.
