Table 2-1. I/O Ports and Peripheral Functions
51 I/O lines. All ports are fully bidirectional except port E, which is input
only.
Each port can serve as either general-purpose I/O or as part of the
microcontroller’s specialized functions, depending on the operating
mode or peripheral functions selected. The functions of ports B, C, and
F and port G bit 7 depend on the operating mode. They serve as
general-purpose I/O lines in single-chip and bootstrap modes and
provide the address and data buses in expanded and special test
modes. The other ports serve as general-purpose I/O out of reset; writes
to control registers enable their special functions.
