Section 9 I/O Ports
9.11.4
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.
In mode 7, if a pin is in the input state in accordance with the settings in PDDDR and LPCR,
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 reset, and in hardware standby mode.
The prior state is retained in software standby mode.
Table 9.24 summarizes the MOS input pull-up states.

Legend:
OFF:
ON/OFF: On when PDDDR = 0, PDPCR = 1, and the pin is not used as a segment driver;
