General Purpose I/O Module

Introduction
Many of the pins associated with the MCF5235 external interface may be used for several different
functions. Their primary functions are to provide external interfaces 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 general purpose I/O pins on the MCF5235 are grouped into 8-bit ports. Some ports do not use
all 8 bits. Each GPIO port has registers that configure, monitor, and control the port pins.
