Section 8 I/O Ports

REJ09B0355-0300
Modes 2 and 6
In modes 2 and 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.
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.

Modes 3 and 7
In modes 3 and 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.
Note:
Modes 3 and 7 cannot be used in the H8S/2240.
Port C pin functions in modes 3 and 7 are shown in figure 8.17.
