3.20 GPIO
Unused bus interface and peripheral pins on the MCF5271 can be used as discrete general-purpose inputs
and outputs. These are managed by a dedicated GPIO module that logically groups all pins into ports
located within a contiguous block of memory-mapped control registers.
All of the pins associated with the external bus 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 this, all 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 on the MCF5271 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.

Signal Descriptions
This section describes signals that connect off chip, including a table of signal properties. For a more
detailed discussion of the MCF5271 signals, consult the
MCF5235 Reference Manual
(MCF5235RM).
4.1
Signal Properties
Table 2
lists all of the signals grouped by function. The “Dir” column is the direction for the primary
function of the pin. Refer to
Section 7, “Mechanicals/Pinouts and Part Numbers
,” for package diagrams.
NOTE
In this table and throughout this document a single signal within a group is
designated without square brackets (i.e., A24), while designations for
multiple signals within a group use brackets (i.e., A[23:21]) and is meant to
include all signals within the two bracketed numbers when these numbers
are separated by a colon.
NOTE
The primary functionality of a pin is not necessarily its default functionality.
Pins that are muxed with GPIO will default to their GPIO functionality.
