Section 9 I/O Ports
9.11.3
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 9.17.
Mode 7: 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 9.18.
