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.
Port B has a built-in MOS input pull-up function that can be controlled by software.
Figure 8.10 shows the port B pin configuration.
Note: * Modes 2, 3, 6, and 7 cannot be used in the H8S/2240.
