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
Chapter 2
Chapter 3
Product Overview
Address Spaces
Addressing Modes
Chapter 4
Chapter 5
Chapter 6
Control Registers
Interrupt Structure
SAM88RCRI Instruction Set
Chapter 1, "Product Overview," is a high-level introduction to the 100% with general product descriptions, as well
as detailed information about individual pin characteristics and pin circuit types.
Chapter 2, "Address Spaces," explains the 100% program and data memory, internal register file, and mapped
control register, and explains how to address them. 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
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 100% 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
Chapter 8
Chapter 9
Chapter 10
Chapter 11
Chapter 12
Chapter 13
Clock Circuits
RESET and Power-Down
I/O Ports
Basic Timer
Timer 1
Watch Timer
LCD Controller/Driver
Chapter 14
Chapter 15
Chapter 16
Chapter 17
Chapter 18
Chapter 19
10-bit ADC
Serial I/O Interface
Electrical Data
Mechanical Data
S3P9228 OTP
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.
