The
S3C8238/C8235/F8235 Microcontroller User's Manual
is designed for application designers and programmers
who are using the S3C8238/C8235/F8235
microcontroller for application development.
It is organized in two main parts:
Part I
Programming Model
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 1, "Product Overview," is a high-level introduction to S3C8238/C8235/F8235
with general product
descriptions, as well as detailed information about individual pin characteristics and pin circuit types.
Part II
Hardware Descriptions
Chapter 4
Chapter 5
Chapter 6
Control Registers
Interrupt Structure
Instruction Set
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 S3C8238/C8235/F8235
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 S3C-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
S3C8238/C8235/F8235
microcontroller. Also included in Part II are electrical, mechanical, Flash MCU, and
development tools data. It has 16 chapters:
Chapter 7
Clock Circuit
Chapter 8
RESET and Power-Down
Chapter 9
I/O Ports
Chapter 10
Basic Timer
Chapter 11
8-bit Timer A/B
Chapter 12
16-bit Timer 1
Chapter 13
Watch Timer
Chapter 14
LCD Controller/Driver
Two order forms are included at the back of this manual to facilitate customer order for S3C8238/C8235/F8235
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.
