3 / 46 page Signal Descriptions MCF5208 ColdFire® Microprocessor Data Sheet, Rev. 1 Freescale Semiconductor 3 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 will default to their GPIO functionality. Table 3.
