Section 8 I/O Ports
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 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.
8.10.3
Modes 1, 2, 4, 5, and 6
In modes 1, 2, 4, 5, and 6, port D pins are automatically designated as data I/O pins.
Note: Modes 2 and 6 cannot be used in the H8S/2240.
Port D pin functions in modes 1, 2, 4, 5, and 6 are shown in figure 8.19.
