Section 9 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 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 9.14.
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 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 9.15.
