• Description: H8S/2345 F-ZTAT Hardware Manual
• Manufacturer: HITACHI [Hitachi Semiconductor]

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.
Port C pin functions in modes 2 and 6 are shown in figure 8.15.
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.
Port C pin functions in modes 3 and 7 are shown in figure 8.16.
Note: * Modes 1 to 3 are not available on the F-ZTAT version.
Modes 2, 3, 6, and 7 are not available on the ROMless version.
