Preface
The S3C80C5/C80C8 Microcontroller User's Manual is designed for application designers and programmers who
are using the S3C80C5/C80C8 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
Instruction Set
Chapter 1, "Product Overview," is a high-level introduction to S3C80C5/C80C8 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
KS88-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 S3C80C5/C80C8 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
S3C80C5/C80C8 microcontroller. Also included in Part II are electrical, mechanical, OTP, and development tools
data. It has eight chapters:
Chapter 7
Clock Circuit
Chapter 11
Chapter 12
Chapter 13
Chapter 14
Timer 1
Counter A
Electrical Data
Mechanical Data
Chapter 8
Chapter 9
Chapter 10
RESET and Power-Down
I/O Ports
Basic Timer and Timer 0
Two order forms are included at the back of this manual to facilitate customer order for S3C80C5/C80C8
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.
