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. Note: Modes 2 and 6 cannot be used in the H8S/2240. Port C pin functions in modes 2 and 6 are shown in figure 8.16.
