General Purpose I/O Module
12.1
Introduction
Many of the pins associated with the MCF5271 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 MCF5271 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.
