10.12.6 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 mode 7. Input pull-up MOS 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 input pull-up MOS for that pin.
Table 10.5 summarizes the input pull-up MOS states.
