汇编语言实现交通灯设计资料

1、利用8255在最小模式下设计实现一个十字路口交通灯显示系统，模拟四个路口红、黄、绿 的亮灭和切换。用protus仿真最小模式：U1212231-NIMI331980863023A14A12A13A15RESETAD0.15READYA16.19INTA/QS1INTRALE/QS0HOLD/GT1BHEHLDA/GT0-DT/R/S1-TESTDEN/S2NMIRDMN/MXWR/LOCKCLKM/IO/S028U2AY0BY1CY2Y3Y4E1Y5E2Y6E3Y71574LS1386423AD0.15253415U3AD1 4AD2/AD38AD4-1314AD617AD718111AD03
