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 S3C94A5/F94A5 with a general product description, and detailed information about individual pin characteristics and pin circuit types. Chapter 2, "Address Spaces," explains the S3C94A5/F94A5 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 S3C94A5/F94A5 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 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 S3C94A5/F94A5 microcontrollers. Also included in part II are electrical, mechanical, MTP, and development tools data. It has 14 chapters: Chapter 7 Chapter 8 Chapter 9 Chapter 10 Chapter 11 Chapter 12 Chapter 13 Clock Circuit RESET and Power-Down I/O Ports Basic Timer 16-bit Timer 0 16-bit Timer 1 8-bit Timer 2 Chapter 14 Chapter 15 Chapter 16 Chapter 17 Chapter 18 Chapter 19 Chapter 20 Watch Timer 10-Bit Analog-To-Digital Converter Serial I/O Interface Electrical Data Mechanical Data S3F94A5 Flash MCU Development Tools Two order forms are included at the back of this manual to facilitate customer order for S3C94A5/F94A5 microcontroller: 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.
