Signal Descriptions
This section describes signals that connect off chip, including a table of signal properties. For a more
detailed discussion of the MCF523
x
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 6, “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.
