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.
