Chapter 3
ColdFire Core
This chapter provides an overview of the microprocessor core of the MCF5253. The chapter describes the
CF2 memory map and register description as it is implemented on the MCF5253. It also includes a full
description of exception handling, data formats, an instruction set summary, and a table of instruction
timings. For detailed information on instructions, see the ColdFire Family Programmer’s Reference
Manual.

Figure 3-1
The processor core is comprised of two separate pipelines that are decoupled by an instruction buffer. The
Instruction Fetch Pipeline (IFP) is responsible for instruction address generation and instruction fetch. The
instruction buffer is a first-in-first-out (FIFO) buffer that holds prefetched instructions awaiting execution
