• Manufacturer Part Number: HD6412350
• Description: (HD6412350 / HD6432351) 16-BIT MICROCONTROLLER
• Manufacturer: Hitachi

Modes 2 and 6 [H8S/2351 Only]: 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 9-17.
Modes 3 and 7 [H8S/2351 Only]: 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 9-18.
