12.1.1 Overview
The MCF5271 ports module controls the configuration for various external pins, including those
used for:
12.1.2 Features
The MCF5271 ports includes these distinctive features:
12.2
The MCF5271 ports control the functionality of several external pins. These pins are listed in
Table 12-2
After reset ports ADDR, DATAH, DATAL, BUSCTL, BS and CS are configured for external
memory. They are available for the user as GPIO if the corresponding registers are set
appropriately. All other ports default to GPIO after reset.

External Signal Description
under the GPIO column.
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.
