Atom? Processor N270 and Mobile Intel? 945GSE Express Chipset Customer Reference Board (CRB) and other components included in the Development Kit. This manual is written for OEMs, system evaluators, and embedded system developers. This document defines all jumpers, headers, LED functions, and their locations on the development board along with subsystem features. This manual assumes basic familiarity in the fundamental concepts involved with installing and configuring hardware for a personal computer system. Note:Read this document in its entirety prior to applying power to the motherboard. Chapter 6 provides quick start procedures. Intel recommends having both the schematic and board present while reading this document. The references in this document correlate to reference designators and board properties of Intel? Atom? Processor N270 and Mobile Intel? 945GSE Express Chipset FAB B Customer Reference Board. This manual is intended to be used with the Development Kit but can also be used to help bring up the Intel? Atom? Processor N270 and Mobile Intel? 945GSE Express Chipset board, although not all associated peripherals will be included with the development board. 1.1Content Overview Chapter 1.0, “ About This Manual” This chapter contains a description of conventions used in this manual. The last few sections explain how to obtain literature and contact customer support. Chapter 2.0, “ Getting Started” This chapter identifies key components, features and specifications. Chapter 3.0, “ Theory of Operation” This chapter provides information on the system design. Chapter 4.0, “ Hardware Reference” This chapter provides a description of development kit primary features, connectors, and configuration settings. Chapter 5.0, “ Software” This chapter provides information on system BIOS and OS support. Chapter 6.0, “ Quick Start” This chapter provides a summary of hardware and power-on instructions for the development kit. 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 7 页，共 36 页 - - - - - - - - - Developer s Kit User Manual 1.2Text Conventions The notations listed in Table 1 may be used throughout this manual. Table 1. Text Conventions Notation Definition # The pound symbol (#) appended to a signal name indicates that the signal is active low. (e.g., PM_BMBUSY#) Variables Variables are shown in italics. Variables must be replaced with correct values. Instructions Instruction mnemonics are shown in uppercase. When you are programming, instructions are not case-sensitive. You may use either uppercase or lowercase. Numbers Hexadecimal numbers are represented by a string of hexadecimal digits followed by the character H. A zero prefix is added to numbers that begin with A through F. (For example, FF is shown as 0FFH.) Decimal and binary numbers are represented by their customary notations. (That is, 255 is a decimal number and 1111 is a binary number. In some cases, the letter B is added for clarity.) Units of Measure A GB KB KmA MB MHz ms mW ns pF W V A F s W The following abbreviations are used to represent units of measure: amps, amperes gigabytes kilobytes kilo-ohms milliamps, milliamperes megabytes megahertz milliseconds milliwatts nanoseconds picofarads watts volts microamps, microamperes microfarads microseconds microwatts Signal Names Signal names are shown in uppercase. When several signals share a common name, an individual signal is represented by the signal name followed by a number, while the group is represented by the signal name followed by a variable (n). For example, the lower chip-select signals are named CS0#, CS1#, CS2#, and so on; they are collectively called CSn#. A pound symbol (#) appended to a signal name identifies an active-low signal. Port pins are represented by the port abbreviation, a period, and the pin number (e.g., P1.0). 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 8 页，共 36 页 - - - - - - - - - Developer s Kit User Manual 1.3Glossary of Acronyms Table 2 defines the acronyms used throughout this document.
