12.2 Introduction
Advance Information
272
Many of the pins associated with the external interface may be used for
several different functions. Their primary function is to provide an
external interface to access off-chip resources. When not used for their
primary functions, many of the pins may be used as general purpose
digital input/output (I/O) pins. In some cases, the pin function is set by
the operating mode, and the alternate pin functions are not supported.
To facilitate the general purpose digital I/O function, these pins are
grouped into 8-bit ports. Each port has registers that configure the pins
for the desired function, monitor the pins, and control the pins within the
ports.
