Description: 带数码管显示的交通灯模拟控制系统设计. 硬件方面：8253产生1HZ的方波，脉冲到8259的IR1端，产生中断，调中断服务子程序。在加入紧急车道后，单脉冲（）连到8259的IRO端，产生一个高级的中断请求信号。
软件方面：主程序先对各个硬件初始化，在开CPU中断，然后空操作，等待中断。执行低级中断（IR1）时，8255的PA口负责选数码管，PB口负责显示数字，用查表法可查到0~9的数码管编码。
采用循环扫描方法，人眼即可看到连续的二位数。当倒计时减到零时，对红绿灯取反。若手动上下拨动单脉冲（）一次，则产生一个高级中断（IR0），程序转而执行此中断处理程序，处理完后返回继续执行低级中断（IR1）。
