9.11.4 MOS Input Pull-Up Function (On-Chip ROM Version Only)
Port D 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 mode 7, and can be specified as on or off on an individual bit basis.
When a PDDDR bit is cleared to 0 in mode 7, setting the corresponding PDPCR 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 9-20 summarizes the MOS input pull-up states.
Note: * Manual reset is only supported in the H8S/2357 ZTAT.
