Preface

The S3C9228/P9228 Microcontrollers User's Manual is designed for application designers and programmers who

are using the S3C9228/P9228 microcontrollers 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 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 S3C9228/P9228 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, internal register file, and mapped control

system stack and user-defined stack operations.

Chapter 3, "Addressing Modes," contains detailed descriptions of the 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 S3C9228/P9228 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 SAM8 product 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

S3C9228/P9228 microcontrollers. Also included in Part II are electrical, mechanical, OTP, and development tools

data. It has 13 chapters:

Chapter 7 Clock Circuits

Chapter 8 RESET and Power-Down

Chapter 9 I/O Ports

Chapter 10 Basic Timer

Chapter 11 Timer 1

Chapter 12 Watch Timer

Chapter 13 LCD Controller/Driver

Chapter 14 10-bit ADC

Chapter 15 Serial I/O Interface

Chapter 16 Electrical Data

Chapter 17 Mechanical Data

Chapter 18 S3P9228 OTP

Chapter 19 Development Tools

Two order forms are included at the back of this manual to facilitate customer order for S3C9228/P9228

microcontrollers: 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.
