General Purpose I/O Module

Introduction
Many of the pins associated with the external interface may be used for several different functions. Their
primary function is to provide an external memory interface to access off-chip resources. When not used
for their primary function, many of the pins may be used as general-purpose digital I/O pins. In some cases,
the pin function is set by the operating mode, and the alternate pin functions are not supported.
The digital I/O pins are grouped into 8-bit ports. Some ports do not use all eight bits. Each port has registers
that configure, monitor, and control the port pins.
