Élan™SC520 Microcontroller Register Set Manual

PREFACE

INTRODUCTION

ÉLAN™SC520 MICROCONTROLLER

The Élan™SC520 microcontroller is a full-featured microcontroller developed for the

general embedded market. The ÉlanSC520 microcontroller combines a 32-bit, low-voltage

Am5x86® CPU with a complete set of integrated peripherals suitable for both real-time and

PC/AT-compatible embedded applications.

PURPOSE OF THIS MANUAL

This manual includes in reference format the complete set of registers required to configure

the ÉlanSC520 microcontroller and control its peripherals. This manual does not document

the Am5x86 processor registers.

Intended Audience

This reference manual is intended primarily for programmers who are developing code for

the ÉlanSC520 microcontroller. Computer software and hardware architects and system

engineers who are designing or are considering designing systems based on this

microcontroller may also be interested in the information contained in this document. For

more information on programming this microcontroller, see the

Élan™SC520

Microcontroller User’s Manual, order #22004.
