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 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.
Note: * Modes 1 to 3 are not available on the F-ZTAT version.
8.7.3
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 8.10.
Note: * Modes 1 to 3 are not available on the F-ZTAT version.
