摘要
在单片机应用系统中,某些场合要求系统具有一定的抗干扰能力。介绍了一种集上电可靠复位,存储系统正常运行时的必要参数,防止程序跑飞等功能于一身的看门狗芯片X25045的控制方法,并给出了接口电路以及用C51语言编写的源程序。
In some cases, the MCU system is expected to be able to deal with the interference of surroundings. The paper presents a method using the clip of Watchdog X25045,which has functions of power-on and reset reliably , storing the system' s parameters normally used and preventing the programs lost. The interface circuit and main programs with C51 language is also given in the paper.
