Preface

The S3C9454B/F9454B Microcontroller User's Manual is designed for application designers and programmers

who are using the S3C9454B/F9454B microcontroller for application development. It is organized in two 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 sections:

Chapter 1 Product Overview

Chapter 2 Address Spaces

Chapter 3 Addressing Modes

Chapter 4 Control Registers

Chapter 5 Interrupt Structure

Chapter 6 SAM88RCRI Instruction Set

Chapter 1, "Product Overview," is a high-level introduction to the S3C9454B/F9454B with a general product

description, and detailed information about individual pin characteristics and pin circuit types.

Chapter 2, "Address Spaces," explains the S3C9454B/F9454B program and data memory, internal register file,

and mapped control registers, and explains how to address them. Chapter 2 also describes working register

addressing, as well as system and user-defined stack operations.

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

the 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 standard 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 S3C9454B/F9454B interrupt structure in detail and further prepares

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

Chapter 6, "SAM88RCRI Instruction Set," describes the features and conventions of the instruction set used for all

S3C9-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 SAM88RCRI product family and are reading this manual for the first time,

we recommend that you first read chapter 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 contains detailed information about the peripheral components of the S3C9454B/F9454B microcontrollers.

Also included in Part II are electrical, mechanical, MTP, and development tools data. It has 10 chapters:

Chapter 7 Clock Circuit

Chapter 8 RESET and Power-Down

Chapter 9 I/O Ports

Chapter 10 Basic Timer and Timer 0

Chapter 11 8-bit PWM

Chapter 12 A/D Converter

Chapter 13 Electrical Data

Chapter 14 Mechanical Data

Chapter 15 S3F945B MTP

Chapter 16 Development Tools

Two order forms are included at the back of this manual to facilitate customer order S3C9454B/F9454B microcon-

trollers: the Mask ROM Order Form, and the Mask Option Selection Form. You can photocopy these forms, fill

them out, and then forward them to your local Samsung Sales Representative.
