For a detailed feature list see the MCF5271 Reference Manual (MCF5271RM).

4 Signal Descriptions

This section describes signals that connect off chip, including a table of signal properties. For a more

detailed discussion of the MCF5271 signals, consult the MCF5271 Reference Manual (MCF5271RM).

4.1 Signal Properties

Table 4 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.
