8.7.1
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 8.9 shows the port B pin configuration.
Note: * Modes 6 and 7 are not available in the ROMless versions.
