已知(A)=40H,执行ADD A,#40H后,(OV)= ( )。
举一反三
- 已知:(30H)=23H,(31H)=13H,(40H)=72H,(41H)=08H 执行: MOV A,30H ADD A,40H DA A MOV 30H,A MOV A,31H ADDC A,41H DA A MOV 31H,A 则结果为:(30H)=______H,(31H)=______H,(40H)=______H,(CY)=______。
- 已知:A=D2H,(40H)=77H,执行指令:ORL A,40H 后,其结果是 H。(填十六进制数)
- MOV A, #40H执行这条指令后,A的内容是( )H
- 假定(SP)=40H ,(39H)=30H,(40H)=60H。执行下列指令:POP DPHPOP DPL后,DPTR的内容为 H。
- 已知:A=D2H,(40H)=77H,执行指令:ORL A,40H后,其结果是
