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的速度往下递减到765398并保持住此数，与此同时利用定时器0以500Ms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“HELLO",到此停止住。-Dynamic scan and Timer 1 in the digital pipe shows start from 765 432 to 1/10 reduced the speed down to 765,398 and hold this number, at the same time using Timer 0 to 500Ms light from top to bottom for water movement When the digital pipe to reduce it to stop, the test board running water stopped and then all the lights start flashing, 3 seconds (with the T0 timer) running water all the lights off, digital tube display "HELLO", this stop living.
