ARM732位嵌入式系统，看门狗溢出产生中断的代码

通过按键喂狗防止溢出复位 看门狗演示程序 在16383个机器周期内必须至少喂狗一次 标准AT89s52单片机试验通过。-Button to feed the dog through the demonstration program to prevent overflow in the watchdog reset 16383 machine cycle to feed the dog at least once a standard AT89s52 microcontroller

定时模式：将WDT设置为定时模式产生定时中断，控制P1.0的输出，使LED周期亮灭。 看门狗模式：将WDT设置成看门狗模式，此时，当看门狗定时器溢出时，将会产生复位。 -Timing mode: WDT setting the timing mode timer interrupt, control the P1.0 output, the LED cycle light off. Watchdog mode: WDT set watchdog mode, at this time, w
