你可曾经为硬件看门狗的复位时间太短,而苦恼过,这个方法帮你解决问题. 用定时器喂狗,如果超过一定时间(程序跑飞,或整个中断都关闭,都会导致定时器不喂狗,导致看门狗的复位,从而延长了看门狗的复位时间)不喂就复位. 程序中我以lcpRD2为例.-you may have to reset the hardware watchdog short time and anguish that this approach help you solve the problem. DOG with timers, if more than a certain time (running fly procedures, or were closed throughout the interruption, it will not lead to the timer DOG, resulting in the reduction watchdog, thereby prolonging the watchdog reset the time) do not feed on the reset. proceedings I lcpRD2 example.

PCI(外设部件互连)是当今个人计算机的主流总线结构，是微型计算机中处理器/存储器与外围控制部件、扩展卡之间的互连接口。PCI局部总线规范是互连机构的协议，也是电气和机械配置的规范。 本书分为9章，涵盖了PCI局部总线规范2.2版及其最新进展，详细介绍了PCI局部总线的原理和操作，内容包括PCI局部总线的基本概念、信号的定义、总线的操作、电气规范、机械规范、配置空间、66 MHz规范、BIOS和PCI-PCI桥等。书中通过大量的时序波形和实例对PCI局部总线的实际应用进行了深入浅出的阐述。 -PCI (peripheral device part interconnection) is now personal computer s mainstream bus structure, is in the microcomputer the processor/memory and between the periphery control portion, the expansion card interconnection connection. The PCI local bus standard is the interconnection organization agreement, is also the standard which the electricity and the machinery dispose. This book divides into 9 chapters, has covered the PCI local bus standard 2.2 edition and the newest progress, introduced the PCI local bus s principle and the operation in detail, the content including the PCI local bus s basic concept, the signal definition, main line s operation, the electricity standard, the mechanical standard, the disposition space, 66 MHz stand
