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.
