USER'S MANUAL

Revision 3

Preface

The

S3C880A/F880A Microcontroller User's Manual

is designed for application designers and programmers who are

using the S3C880A/F880A microcontroller for application development.

It is organized in two main parts:

Part I

Programming Model

Part II

Hardware Descriptions

Part I contains software-related information to familiarize you with the microcontroller's architecture, programming

model, instruction set, and interrupt structure. It has six chapters:

Chapter 1

Chapter 2

Chapter 3

Product Overview

Address Spaces

Addressing Modes

Chapter 4

Chapter 5

Chapter 6

Control Registers

Interrupt Structure

SAM8 Instruction Set

Chapter 1, "Product Overview," is a high-level introduction to S3C880A/F880A with general product descriptions, as

well as detailed information about individual pin characteristics and pin circuit types.

Chapter 2, "Address Spaces," describes program and data memory spaces, the internal register file, and register

addressing. Chapter 2 also describes working register addressing, as well as system stack and user-defined stack

operations.

Chapter 3, "Addressing Modes," contains detailed descriptions of the addressing modes that are supported by the

S3C8-series CPU.

Chapter 4, "Control Registers," contains overview tables for all mapped system and peripheral control register values,

as well as detailed one-page descriptions in a standardized format. You can use these easy-to-read, alphabetically

organized, register descriptions as a quick-reference source when writing programs.

Chapter 5, "Interrupt Structure," describes the S3C880A/F880A interrupt structure in detail and further prepares you

for additional information presented in the individual hardware module descriptions in Part II.

Chapter 6, "SAM8 Instruction Set," describes the features and conventions of the instruction set used for all S3C8-

series microcontrollers. Several summary tables are presented for orientation and reference. Detailed descriptions of

each instruction are presented in a standard format. Each instruction description includes one or more practical

examples of how to use the instruction when writing an application program.

A basic familiarity with the information in Part I will help you to understand the hardware module descriptions in Part

II. If you are not yet familiar with the S3C8-series microcontroller family and are reading this manual for the first time,

we recommend that you first read Chapters 1–3 carefully. Then, briefly look over the detailed information in Chapters

4, 5, and 6. Later, you can reference the information in Part I as necessary.

Part II "hardware Descriptions," has detailed information about specific hardware components of the S3C880A/F880A

microcontroller. Also included in Part II are electrical, mechanical, MTP, and development tools data. It has 11

chapters:

Chapter 7

Chapter 8

Chapter 9

Chapter 10

Chapter 11

Chapter 12

Clock Circuits

nRESET and Power-Down

I/O Ports

Basic Timer and Timer 0

Timer A
