9.10.3 Pin Functions
Mode 7 (On-Chip ROM Version Only): 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 a PCDDR bit to 1 makes the corresponding port C pin an output port, while
clearing the bit to 0 makes the pin an input port.
Port C pin functions in mode 7 are shown in figure 9-16.

Mode 6 (On-Chip ROM Version Only): 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 a PCDDR bit to 1 makes the corresponding port C pin an
address output, while clearing the bit to 0 makes the pin an input port.
Port C pin functions in mode 6 are shown in figure 9-17.
