利用动态扫描和定时器1在数码管上显示出从765432开始以1/10秒的速度往下递减直至765398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，

当数码管上数减到停止时，实验板上流水灯也停止然后全部开始闪烁，

3秒后（用T0定时）流水灯全部关闭、数码管上显示出"HELLO"。到此保持住。

设晶振频率为12MHz。-Dynamic scan and Timer 1 digital pipe shows from 765,432 began to 1/10 seconds speed down decreasing until 765,398 and maintain display this few, meantime use Timer 0 to 500MS speed pipelining lamp from on to under movement when digital pipe few reduced stopped, experiment board pipelining lamp also stop then Full start blinking, 3 seconds (using T0 Timing) pipelining lamp all closed, digital pipe shown "HELLO". This maintaining live. Set crystal frequency 12MHz.
