This manual documents the MICROcontrolLER profile of version 7 of the ARM® Architecture, the ARMv7-M architecture profile. For short definitions of all the ARMv7 profiles see About the ARMv7 architecture, and architecture profiles on page A1-20.ARMv7 is documented as a set of architecture profiles. The profiles are defined as follows: ARMv7-A The application profile for systems supporting the ARM and Thumb instruction sets, and requiring virtual address support in the memory management model. ARMv7-R The realtime profile for systems supporting the ARM and Thumb instruction sets, and requiring physical address only support in the memory management model ARMv7-M The MICROcontrolLER profile for systems supporting only the Thumb instruction set, and where overall size and deterministic operation for an implementation are more important than absolute performance. While profiles were formally introduced with the ARMv7 development, the A-profile and R-profile have implicitly existed in earlier versions, associated with the Virtual Memory System Architecture (VMSA) and Protected Memory System Architecture (PMSA) respectively.

In this presentation, we will look at what the Serial Peripheral Interface, otherwise known as the SPI, is. and how it is used to communicate data to and from the PICmicro MICROcontrolLER.SPl is frequently used when few 1/O lines are available, but communication between two or more devices must be fast and easy to implement.In this presentation, we will discuss the following topics: We will first cover an Overview of SPI This section of the tutorial will introduce you to SPI and its concepts.Next, we will examine the use of SPI on the PICmicro MCU.The details of how SPI is implemented on a PICmicro device will be examined.Then, a Code Walkthrough will be given.The walkthough will explore code for both an SPI Master and SPI Slave. The example will have the Master generate data for sending to the slave.Finally, there will be a few resources given at the end of the presentation. These resources will allow you to explore in more detail the SPI interface

说明：原文（英语）来自Freescale Semiconductor，Inc.的应用文档，作者，T.C.Lun，Applications Engineering，MICROcontrolLER Division，Hong Kong.文档分为下列几个部分：PART 1 观EMC PART 2器件的选择及电路的设计PART 3印刷电路板layout技术附录A EMC术语表附录B 抗干扰测量标准第一部分 EMI和EMC纵览：在现代电子设计中EMI是一个主要的问题。为抗干扰，设计者婴么除掉干扰源，要么保护受影响的电路，最终的目的都是为了达到电磁兼容的目的仅仅达到电磁兼容也许还不够。虽然电路工作在板级，但它有可能对系统的共他部件辐射噪音、干扰，从而引起系统级的问题。此外，系统毅或者设备级的EMC不得不满足某些辐射标准，以便不影响其他设备。许多发达国家在电子产品上有非常严格的EMC标准。为了达到这些要求，设计者必须考虑从板极开始的EMI抑制。一个简单的EMI模型包含三个元素，如图1所示：1.EMI源2.耦合路径3.感应体

本书属于8051进阶级书籍，适合对单片机已经有一些经验的读者，或横跨软硬件的工程师阅读。我们希望您在阅读本书时，已经对8051的结构与程序有基本的认识，例如SFR、bit addressable、SBUF等等。本书共分成三大部分：第一部分是应用研究篇，介绍8051单片机的诸多设计理念与硬件保护手段。想要以子之矛攻子之盾，在这里有第一手的解答。我们也提到与硬件保护始终对立的逆向工程与8051之间的关系。最后还有一章专门提到8051的优势与缺憾。8051当初被人称道的功能至今被贬为重大瑕疵，为何如此？请看我们的深入分析。第二部分是介绍以FLAG51为主体的烧录器，包括Atmel Flash MICROcontrolLER的烧录、EPROM的烧录以及EPROM的烧录等，我们很乐意地公布这些烧录程序，而且是100%的源代码公布。以前我们彻底研究别人的程序为的是理解当初设计者的理念。今天我们公布程序内容，欢迎您来研究我们写的程序，如果您是用心的读者绝对可以从中获得更多的启示。第三部分是历年来我们接触到设计项目的心得以及我们对一些问题的看法。更多相关内容已全部上传：8051单片机彻底研究-基础篇：http://dl.21ic.com/download/8051-330965.html 8051单片机彻底研究-经验篇：http://dl.21ic.com/download/8051-330966.html 8051单片机彻底研究-入门篇：http://dl.21ic.com/download/8051-330967.html 8051单片机彻底研究-实习篇：http://dl.21ic.com/download/8051-330969.html 8051单片机C语言软件设计的艺术：http://dl.21ic.com/download/8051-330970.html
