S3F80JB MICROCONTROLLER iii
Preface
The S3F80JB Microcontroller User's Manual is designed for application designers and programmers who are
using
S3F80JB 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 2 Address Spaces
Chapter 3 Addressing Modes
Chapter 4 Control Registers
Chapter 5 Interrupt Structure
Chapter 6 Instruction Set
Chapter 1, "Product Overview," is a high-level introduction to
S3F80JB 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
S3F80JB 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 S3F8-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 S3F8-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
S3F80JB
microcontroller. Also included in Part II are electrical, mechanical, MTP, and development tools data. It has 14
chapters:
Chapter 7 Clock Circuits
Chapter 8 RESET
Chapter 9 I/O Ports
Chapter 10 Basic Timer and Timer 0
Chapter 11 Timer 1
Chapter 12 Counter A
Chapter 13 Timer 2
Chapter 14 Comparator
Chapter 15 Embedded Flash Memory Interface
Chapter 16 Low Voltage Detector
Chapter 17 Electrical Data-4MHz
Chapter 18 Electrical Data-8MHz
Chapter 19 Mechanical Data
Chapter 20
Development Tools Data
