Section 9 I/O Ports
9.8 Port B
9.8.1 Overview
Port B is an 8-bit I/O port. Port B pins also function as address bus outputs. The pin functions
depend on the operating mode.
Port B has an on-chip MOS input pull-up function that can be controlled by software.
Figure 9.7 shows the port B pin configuration.
