指出下列指令的本质区别。
MOVA,30H
MOVA,#30H
MOV31H,R0
MOV31H,@R0
MOVA,30H
MOVA,#30H
MOV31H,R0
MOV31H,@R0
举一反三
- 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)=?
- 指令 MOV R0,20H 执行前 (R0)=30H, (20H)=38H,执行后(R0)=?
- 指出下列指令的本质区别。 MOV A,30H MOV A,#30H MOV 31H,R0 MOV 31H,@R0
- 指出下列指令的本质区别。 MOV A,30H MOV A,#30H MOV 31H,R0
- 假设(30H)=60H,(60H)=55H,则执行下列指令后,(A)=H,MOV R0,30HMOV A,@R0
