About This Book
The primary objective of this user's manual is to define the functionality of the MCF5272
processors for use by software and hardware developers.
The information in this book is subject to change without notice, as described in the
disclaimers on the title page of this book. As with any technical documentation, it is the
readers' responsibility to be sure he is using the most recent version of the documentation.

Audience
This manual is intended for system software and hardware developers and applications
programmers who want to develop products with the MCF5272. It is assumed that the
reader understands operating systems, microprocessor system design, basic principles of
software and hardware, and basic details of the ColdFire
Organization
Following is a summary and brief description of the major sections of this manual:
• Chapter 1, "Overview," includes general descriptions of the modules and features
incorporated in the MCF5272, focussing in particular on new features.
• Chapter 2, "ColdFire Core," provides an overview of the microprocessor core of the
MCF5272. The chapter describes the organization of the Version 2 (V2) ColdFire
5200 processor core and an overview of the program-visible registers (the
programming model) as they are implemented on the MCF5272. It also includes a
full description of exception handling and a table of instruction timings.
• Chapter 3, "Hardware Multiply/Accumulate (MAC) Unit," describes the MCF5272
multiply/accumulate unit, which executes integer multiply, multiply-accumulate,
and miscellaneous register instructions. The MAC is integrated into the operand
execution pipeline (OEP).
• Chapter 4, "Local Memory." This chapter describes the MCF5272 implementation
of the ColdFire V2 local memory specification. It consists of three major sections,
as follows.
