The following table lists all the MCF5227x pins grouped by function. The direction column is the direction for the primary
function of the pin only. Refer to
discussion of the MCF5227x signals, consult the MCF52277 Reference Manual (MCF52277RM).

Signal Multiplexing
In this table and throughout this document a single signal within a group is designated
without square brackets (i.e., FB_A23), while designations for multiple signals within a
group use brackets (i.e., FB_A[23:21]) and is meant to include all signals within the two
bracketed numbers when these numbers are separated by a colon.
The primary functionality of a pin is not necessarily its default functionality. Most pins that
are muxed with GPIO will default to their GPIO functionality. See
exceptions.
