1已知(R0)=30H,求A,R4,30H,31H的内容MOVA,#10H;MOVR4,#36H;MOV@R0,#7AH;MOV31H,#01H2已知(A)=40H,(40H)=42HMOVR0,A;MOVA,@R0;MOV30H,A;求(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( ) A: 、0 B: H C: H D、F D: H E: O F: O G: O H: R1,#30H I: 40H,#0 J: @R1,40H <br/>A、40H B、30H
- 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:
- 指令 MOV R0,20H 执行前 (R0)=30H, (20H)=38H,执行后(R0)=?
