Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" off the road or making it to the nearest service station. Redundant systems, watchdog TIMERs, and other controlcircuits are used to reroute signals and perform other functions that ensure that a vehicle can safely make it off the road when afailure occurs.

什么是JTAG 到底什么是JTAG呢？ JTAG(Joint Test Action Group)聯(lián)合測(cè)試行動(dòng)小組)是一種國際標(biāo)準(zhǔn)測(cè)試協(xié)議（IEEE 1149.1兼容），主要用于芯片內(nèi)部測(cè)試。現(xiàn)在多數(shù)的高級(jí)器件都支持JTAG協(xié)議，如DSP、FPGA器件等。標(biāo)準(zhǔn)的JTAG接口是4線：TMS、 TCK、TDI、TDO，分別為模式選擇、時(shí)鐘、數(shù)據(jù)輸入和數(shù)據(jù)輸出線。 JTAG最初是用來對(duì)芯片進(jìn)行測(cè)試的，基本原理是在器件內(nèi)部定義一個(gè)TAP（Test Access Port�測(cè)試訪問口）通過專用的JTAG測(cè)試工具對(duì)進(jìn)行內(nèi)部節(jié)點(diǎn)進(jìn)行測(cè)試。JTAG測(cè)試允許多個(gè)器件通過JTAG接口串聯(lián)在一起，形成一個(gè)JTAG鏈，能實(shí)現(xiàn)對(duì)各個(gè)器件分別測(cè)試。現(xiàn)在，JTAG接口還常用于實(shí)現(xiàn)ISP（In-System rogrammable�在線編程），對(duì)FLASH等器件進(jìn)行編程。 JTAG編程方式是在線編程，傳統(tǒng)生產(chǎn)流程中先對(duì)芯片進(jìn)行預(yù)編程現(xiàn)再裝到板上因此而改變，簡化的流程為先固定器件到電路板上，再用JTAG編程，從而大大加快工程進(jìn)度。JTAG接口可對(duì)PSD芯片內(nèi)部的所有部件進(jìn)行編程 JTAG的一些說明 通常所說的JTAG大致分兩類，一類用于測(cè)試芯片的電氣特性，檢測(cè)芯片是否有問題；一類用于Debug；一般支持JTAG的CPU內(nèi)都包含了這兩個(gè)模塊。 一個(gè)含有JTAG Debug接口模塊的CPU，只要時(shí)鐘正常，就可以通過JTAG接口訪問CPU的內(nèi)部寄存器和掛在CPU總線上的設(shè)備，如FLASH，RAM，SOC（比如4510B，44Box，AT91M系列）內(nèi)置模塊的寄存器，象UART，TIMERs，GPIO等等的寄存器。 上面說的只是JTAG接口所具備的能力，要使用這些功能，還需要軟件的配合，具體實(shí)現(xiàn)的功能則由具體的軟件決定。 例如下載程序到RAM功能。了解SOC的都知道，要使用外接的RAM，需要參照SOC DataSheet的寄存器說明，設(shè)置RAM的基地址，總線寬度，訪問速度等等。有的SOC則還需要Remap，才能正常工作。運(yùn)行Firmware時(shí)，這些設(shè)置由Firmware的初始化程序完成。但如果使用JTAG接口，相關(guān)的寄存器可能還處在上電值，甚至?xí)r錯(cuò)誤值，RAM不能正常工作，所以下載必然要失敗。要正常使用，先要想辦法設(shè)置RAM。在ADW中，可以在Console窗口通過Let 命令設(shè)置，在AXD中可以在Console窗口通過Set命令設(shè)置。

The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct with minimal performance penalty. With their 144-pin package, low power consumption, various 32-bit TIMERs, 8-channel 10-bit ADC, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available fast GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary.
