利用动态扫描和定时器1在数码管上显示出从765432开始以1 秒的速度往下递减直至764987并保持显示此数，与此同时利用定时器0以500MS速度进行流水灯从上至下移动，同时蜂鸣器发声，当数码管上数减到停止时，实验板上流水灯全部闪烁5次，数码管全熄灭。单片机进入休眠状态。

-Dynamic scan and Timer 1 on the digital display of 1　from the 765,432 begin to decline until the second speed down and keep the show this number 764,987, while the use of Timer 0 to 500MS speed of light from top to bottom water Mobile, same time buzzer, when the LED stops on the reduced number of experimental water board lights all flash 5 times, the digital full-out.
