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 9-14.
9.9.4
Port B has a on-chip MOS input pull-up function that can be controlled by software. This MOS input pull-up function can
be used in modes 6 and 7, and can be specified as on or off on an individual bit basis.
When a PBDDR bit is cleared to 0 in mode 6 or 7, setting the corresponding PBPCR bit to 1 turns on the MOS input pull-
up for that pin.
The MOS input pull-up function is in the off state after a power-on reset, and in hardware standby mode. The prior state is
retained after a manual reset*, and in software standby mode.
Table 9-16 summarizes the MOS input pull-up states.
Note: * Manual reset is only supported in the H8S/2357 ZTAT.

Legend:
OFF:
ON/OFF: On when PBDDR = 0 and PBPCR = 1; otherwise off.
Note:
*
MOS Input Pull-Up Function (On-Chip ROM Version Only)
MOS input pull-up is always off.
Manual reset is only supported in the H8S/2357 ZTAT.
