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 a PBDDR bit is cleared to 0 (input port setting) in mode 2, 3, 6, or 7, setting the
corresponding PBPCR bit to 1 turns on the MOS input pull-up for the corresponding pin.
PBPCR 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.
9.9.3
Modes 1, 4, and 5
In modes 1, 4, and 5, port B pins are automatically designated as address outputs.
Port B pin functions in modes 1, 4, and 5 are shown in figure 9.12.
