试求下列程序依次运行后有关单元中的内容。
MOV 20H,# A5H ;A5H→(20H),字节地址(20H)=A5H=10100101B
MOV C,00H ;位地址(00H)=1,(00H)→C,C=1
ANL C,/04H ;位地址(04H)=0,CA()→C,C=1(刷新)
CPL 07H ;()→(07H),(07H)=0,字节地址(20H)=00100101B=25H
SETB 01H ;(01H)=1,字节地址(20H)=00100111B=27H
MOV A,20H ;字节地址(20H)→A,A=00100111B=27H
RLC A ;A带Cy左移,A=01001111B,Cy=0
MOV 02H,C ;C→(02H),(02H)=0,字节地址(20H)=00100011B=23H
