PREFACE

The M68020 User’s Manual describes the capabilities, operation, and programming of the

MC68020 32-bit, second-generation, enhanced microprocessor and the MC68EC020 32-

bit, second-generation, enhanced embedded microprocessor.

Throughout this manual, “MC68020/EC020” is used when information applies to both the

MC68020 and the MC68EC020. “MC68020” and “MC68EC020” are used when

information applies only to the MC68020 or MC68EC020, respectively.

For detailed information on the MC68020 and MC68EC020 instruction set, refer to

M68000PM/AD, M68000 Family Programmer’s Reference Manual.

This manual consists of the following sections:

Section 1 Introduction

Section 2 Processing States

Section 3 Signal Description

Section 4 On-Chip Cache Memory

Section 5 Bus Operation

Section 6 Exception Processing

Section 7 Coprocessor Interface Description

Section 8 Instruction Execution Timing

Section 9 Applications Information

Section 10 Electrical Characteristics

Section 11 Ordering Information and Mechanical Data

Appendix A Interfacing an MC68EC020 to a DMA Device That Supports a Three-Wire

NOTE

In this manual, assert and negate are used to specify forcing a

signal to a particular state. In particular, assertion and assert

refer to a signal that is active or true; negation and negate

indicate a signal that is inactive or false. These terms are used

independently of the voltage level (high or low) that they

represent.
