Port B is an 8-bit I/O port. Port B has an address bus output function, and the pin functions change
according to the operating mode. However, in the H8S/2350, port B pins function only as address
outputs.
Port B has a built-in MOS input pull-up function that can be controlled by software (H8S/2351
only).
Figure 9.11 shows the port B pin configuration.
