指出下列指令的本质区别。 MOV A,30H MOV A,#30H MOV 31H,R0
举一反三
- 指出下列指令的本质区别。 MOV A,30H MOV A,#30H MOV 31H,R0
- 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)=______。
- 指令 MOV R0,20H 执行前 (R0)=30H, (20H)=38H,执行后(R0)=?
- 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:
