Section 8 I/O Ports
Mode 6^*: In mode 6, port C pins function as address outputs or input ports. Input or output can be
specified on an individual bit basis. Setting PCDDR bits to 1 makes the corresponding port C pins
address outputs, while clearing the bits to 0 makes the pins an input ports.
Port C pin functions in mode 6 are shown in figure 8.15.

Mode 7^*: In mode 7, port C pins function as I/O ports. Input or output can be specified for each
pin on an individual bit basis. Setting PCDDR bits to 1 makes the corresponding port C pins
output ports, while clearing the bits to 0 makes the pins input ports.
Port C pin functions in mode 7 are shown in figure 8.16.
