Port D MOS Pull-Up Control Register (PDPCR)
PDPCR is an 8-bit readable/writable register that controls the MOS input pull-up function
incorporated into port D on an individual bit basis.
When a PDDDR bit is cleared to 0 (input port setting) in mode 7, setting the corresponding
PDPCR bit to 1 turns on the MOS input pull-up for the corresponding pin.
PDPCR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.

Modes 4 to 6: In modes 4 to 6, port D pins are automatically designated as data I/O pins.
Port D pin functions in modes 4 to 6 are shown in figure 9-16.
Mode 7: In mode 7, port D pins function as I/O ports. Input or output can be specified for each pin
on an individual bit basis. Setting a PDDDR bit to 1 makes the corresponding port D pin an output
port, while clearing the bit to 0 makes the pin an input port.
