3 Signal Descriptions
The following table lists all the MCF5208 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 MCF5208 signals, consult the MCF5208 Reference Manual
(MCF5208RM).
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 default to their GPIO functionality.
