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 3 or 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 power-on reset, and in hardware standby mode. It retains its
prior state after a manual reset, and in software standby mode.
9.11.3 Pin Functions
Modes 1, 4, and 5 [H8S/2351]; Modes 1, 2, 4, 5, and 6 [H8S/2351]: In modes 1, 2, 4, 5, and 6,
port D pins are automatically designated as data I/O pins.
Port D pin functions in modes 1, 2, 4, 5, and 6 are shown in figure 9-20.

Modes 3 and 7 [H8S/2351 Only]: In modes 3 and 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.
