Section 8 I/O Ports
8.10.4
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 modes 3 and 7, and can be specified as on or off on an
individual bit basis.
When a PDDDR bit is cleared to 0 in mode 3 or 7, 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 power-on reset, and in hardware standby
mode. The prior state is retained after a manual reset, and in software standby mode.
Note: Modes 2, 3, 6, and 7 cannot be used in the H8S/2240.
Table 8.18 summarizes the MOS input pull-up states.
