10B.10.4 MOS Input Pull-Up Function
Port D has a built-in 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 by a manual reset or in software standby mode.
Table 10B.19 summarizes the MOS input pull-up states.
