10.12.7 Port D Input Pull-Up MOS States
Port D has a built-in input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be used in modes 3 and 7. The input pull-up MOS can be specified as
on or off on a bit-by-bit basis.
In modes 3 and 7, when a PDDDR bit is cleared to 0, setting the corresponding PDPCR bit to 1
turns on the input pull-up MOS for that pin.
Table 10.6 summarizes the input pull-up MOS states.
