Signal Descriptions

The following table lists all the MCF537x pins grouped by function. The “Dir” column is the direction for

the primary function of the pin only. Refer to Section 4, “Mechanicals and Pinouts,” for package diagrams.

For a more detailed discussion of the MCF537x signals, consult the MCF5373 Reference Manual

(MCF5373RM).

NOTE

In this table and throughout this document a single signal within a group is

designated without square brackets (i.e., A23), 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.
