Preface
The
S3C9498/F9498 Microcontroller User's Manual
is designed for application designers and programmers who are
using the S3C9498/F9498 microcontroller for application development. It is organized in two 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 S3C9498/F9498 with a general product description,
and detailed information about individual pin characteristics and pin circuit types.
Chapter 2, "Address Spaces," explains the S3C9498/F9498 program and data memory, internal register file, and
mapped control registers, and explains how to address them. Chapter 2 also describes working register addressing,
as well as system and user-defined stack operations.
Chapter 3, "Addressing Modes," contains detailed descriptions of the six 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 S3C9498/F9498 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 ins truction 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 SAM88RCRI 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 contains detailed information about the peripheral components of the S3C9498/F9498 microcontrollers. Also
included in part II are electrical, mechanical, MTP, and development tools data. It has 14 chapters:
Chapter 7
