系统模块详细设计与调试
1 在主程序中要分别对8254和8255初始化编程。
具体如下：
8254控制字：
MOV DX,PORT_8253
MOV AL,00110101B ;写入控制字，0通道，方式2
OUT DX,AL
MOV DX,PORT_0
MOV AL,00H
OUT DX,AL
MOV AL,10H
OUT DX,AL
MOV DX,PORT_8253
MOV AL,01110111B ;1通道，方式3
OUT DX,AL
MOV DX,PORT_1
MOV AL,00H
OUT DX,AL
MOV AL,10H
OUT DX,AL
8255控制字：
MOV DX,PORT_8255 ;8255初始化
MOV AL,80H
OUT DX,AL
