Features

3 Features

For a detailed feature list see the MCF5275 Reference Manual (MCF5275RM).

4 Signal Descriptions

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

detailed discussion of the MCF5275 signals, consult the MCF5275 Reference Manual (MCF5275RM).

Table 2 lists the signals for the MCF5275 in functional group order. The “Dir” column is the direction for

the primary function of the pin. Refer to Section 6, “Mechanicals/Pinouts,” 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.
