Port C is an 8-bit I/O port. Port C has an address bus output function, and the pin functions change
according to the operating mode. However, in the H8S/2350, port C pins function only as address
outputs.
Port C has a built-in MOS input pull-up function that can be controlled by software (H8S/2351
Only).
Figure 9.15 shows the port C pin configuration.
