9.10 Port C

Section 9 I/O Ports

9.10.1 Overview

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.
