Answer 1

ST BIT P1.3 ;定义IO口
OE BIT P1.1
EOC BIT P1.2
DI bit P3.0
E bit P3.2
Rw bit P3.1
res bit p1.0
X EQU 40H ; ;定义变量
y EQU 42H
UPD EQU 30H
DOD EQU 31H
org 00h ;定义子程序地址,00H是单片机复位开始的地址
ajmp main ;无条件跳转到main 程序段
org 0030h 定义子程序地址
MAIN: nop ;main就子程序标号,NOP是空指令占用1指令周期
SETB EOC ;;EOC BIT P1.2置1
MOV X,#00H ;把0送X

其它参考<<51单片机汇编语言>>
