单片机汇编语言的跳转
程序代码:
ORG 8100H AJMP MAIN ORG 8003H AJMP INT MAIN: SETB EA SETB EX0 CLR IT0 LOOP: MOV R0,#0F3H MOV P1,R0 MOV R7,#1EH LOOP1: LCALL DELAY DJNZ R7,LOOP1 MOV R0,#0F5H MOV P1,R0 MOV R7,#05H LOOP2: LCALL DELAY DJNZ R7,LOOP2 MOV R0,#0DEH MOV P1,R0 MOV R7,#1EH LOOP3: LCALL DELAY DJNZ R7,LOOP3 MOV R0,#0FEH MOV P1,R0 MOV R7,#05H LOOP4: LCALL DELAY DJNZ R7,LOOP4 AJMP MAIN DELAY: MOV R5,#0 DEL1: MOV R6,#0 DEL2: DJNZ R6,DEL2 DJNZ R5,DEL1 RET INT: MOV P1,#0F6H MOV R7,#0AH T11: ACALL DELAY DJNZ R7,T11 MOV P1,R0 REIT: END怎么 这跳转不能实现呢?
