Mode 6: In mode 6, port C pints function as address outputs or input ports and I/O can be
specified in bit units. When each bit in PCDDR is set to 1, the corresponding pin functions as an
address output and when the bit cleared to 0, the pin functions as an input port.
Figure 9-13 shows the port C pin functions.
