9.11.6 Port D MOS Input Pull-Up States
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. MOS input pull-up can be specified as on or off on a
bit-by-bit basis.
In mode 7, when a PDDDR bit is cleared to 0, setting the corresponding PDPCR bit to 1 turns on
the MOS input pull-up for that pin.
Table 9.5 summarizes the MOS input pull-up states.
