已知 (A)=22H,(30H)=66H 执行下列指令后的结果 MOV A,#30H
(A)=30H
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)=______。
- 执行如下三条指令后,30H单元的内容是( ) MOV R1,#30H MOV 40H,#0EH MOV @R1,40H
- 执行如下三条指令①MOV R1,#30H ② MOV 40H,#0EH③MOV @R1,40H后,30H单元的内容是:
- 根据下列程序段运行情况,将运行结果和指令分别补充完整。 (1)( );(A)=10H ( );(B)=10H ( );(A)=20H MOV 23H,A;(23H)=20H ( );(A)=21H MOV 24H,A;(24H)=21H INC A ;(A)=22H ( );(25H)= 22H (2)MOV A,#50H;(A)=( )H MOV R0,A;(R0)=( )H MOV @R0,#30H;(50H)=( )H ADD A,@R0;(A)=( )H MOVX @R0,A;(50H)=( )H
- 如果(A)=5CH,(R0)=30H,(30H)=7AH,执行XCHD A, @R0;结果(A)=_______H,((R0))=_______H。
