9.11.3 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.
