3、 ,再执行 程序。8)已知程序执行前有A=01H,SP=52H,(51H)=FFH,(52H)=FFH。下述程序执行后: POP DPH POP DPL MOV DPTR,#3000H RL A MOV B,A MOVC A,@A+DPTR PUSH A
4、MOV A,B INC A MOVC A,@A+DPTR PUSH A RET ORG 3000H DB 10H,80H,30H,80H,50H,80H 请问:A=(),SP=(),(51H)=(),(52H)=(),PC=()。9)如果DPTR=507BH,SP=32H,(30H)=50H,(31H)=5FH,(32H)=3CH,则执行下列指令后:
5、 POP DPH POP DPL POP SP 则:DPH=(),DPL=(),SP=()10)假定A=83H,(R0)=17H,(17H)=34H,执行以下指令: ANL A,#17H ORL 17H,A XRL A,@R0 CPL
