用汇编语言在按钮计数器的程序里面加几条指令让按钮计数变成按五次或者十次

程序： ORG 0000H LJMP START ORG 000BH LJMP T_0 ORG 0030H START: MOV DPTR,#TABLE MOV SP,#60 MOV TH0,#0FFH MOV TL0,#0F0H SETB EA SETB ET0 MOV TMOD,#05H SETB TR0 LOOP: MOV A,TL0 SUBB A,#0F0H MOV B,#100 DIV AB MOVC A,@A+DPTR MOV P2,#00001101B MOV P1,A LCALL DELAY4MS MOV A,B MOV B,#10 DIV AB MOVC A,@A+DPTR MOV P2,#00001011B MOV P1,A LCALL DELAY4MS MOV A,B MOVC A,@A+DPTR MOV P2,#00000111B MOV P1,A LCALL DELAY4MS LJMP LOOP T_0: PUSH ACC PUSH DPH PUSH DPL CPL P3.0 MOV TH0,#0FFH MOV TL0,#0F0H POP DPL POP DPH POP ACC RETI DELAY4MS: MOV R5,#10 DELAY_LOOP1: MOV R4,#200 DELAY_LOOP2:DJNZ R4,DELAY_LOOP2 DJNZ R5,DELAY_LOOP1 RETI TABLE:DB 3FH,06H,5BH,4FH,66H DB 6DH,7DH,07H,7FH,6FH END
