Pin Functions

Modes 7 (On-Chip ROM Version Only): In mode 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.

Port D pin functions in mode 7 are shown in figure 9-20.

Modes 4 to 6*: In modes 4 to 6, port D pins are automatically designated as data I/O pins.

Port D pin functions in modes 4 to 6 are shown in figure 9-21.

Note: * Mode 6 is provided in the on-chip ROM version only.
