Pin Functions

Port D pins also function as the pins for data I/Os. The correspondence between the register
specification and the pin functions is shown below.

PD7/D15, PD6/D14, PD5/D13, PD4/D12, PD3/D11, PD2/D10, PD1/D9, PD0/D8
The pin function is switched as shown below according to the operating mode, bit EXPE, and bit
PDDDR.

Port D MOS Input Pull-Up States

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 mode 7. MOS input pull-up can be specified as on or off on a
bit-by-bit basis.
In mode 7, when a PDDDR bit is cleared to 0, setting the corresponding PDPCR bit to 1 turns on
the MOS input pull-up for that pin.
Table 9.5 summarizes the MOS input pull-up states.

Legend:
OFF: MOS input pull-up is always off.
On/Off: On when PDDDR = 0 and PDPCR = 1; otherwise off.
