Samsung S3C84E5 user manual Part Programming Model, Uart, Iii

Preface

The S3C84E5/C84E9/P84E9 Microcontroller User's Manual is designed for application designers and programmers who are using the S3C84E5/C84E9/P84E9 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	Product Overview	Chapter 4	Control Registers
Chapter 2	Address Spaces	Chapter 5	Interrupt Structure
Chapter 3	Addressing Modes	Chapter 6	Instruction Set

Chapter 1, "Product Overview," is a high-level introduction to S3C84E5/C84E9/P84E9 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 S3C84E5/C84E9/P84E9 interrupt structure in detail and further prepares you for additional information presented in the individual hardware module descriptions in Part II.

Chapter 6, "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 S3C84E5/C84E9/P84E9 microcontroller. Also included in Part II are electrical, mechanical, OTP, and development tools data. It has 14 chapters:

Chapter 7	Clock Circuit	Chapter 14	Watch Timer
Chapter 8	RESET and Power-Down	Chapter 15	A/D Converter
Chapter 9	I/O Ports	Chapter 16	Low Voltage Reset
Chapter 10	Basic Timer	Chapter 17	Electrical Data
Chapter 11	8-bit Timer A/B	Chapter 18	Mechanical Data
Chapter 12	16-bit Timer 1(0,1)	Chapter 19	S3P84E9 OTP version
Chapter 13	UART	Chapter 20	Development Tools

Two order forms are included at the back of this manual to facilitate customer order for S3C84E5/C84E9/P84E9 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.
