执行指令MOV A, #10H 结果为
举一反三
- 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
- 【填空题】若(R0)=10H,(10H)=1EH,(A)=29H,执行完“XCHD A,@R0”指令后,则(A)=()H,(10H)=()H
- 已知相应单元的内容如下,请写出每条指令执行后的结果。 设(A)=40H;(R0)=50H;(40H)=30H;(50H)=10H。 MOV A,#20H ;(A)=______ MOV A,40H ;(A)=______ MOV A,R0 ;(A)=______ MOV A,@R0 ;(A)=______
- 若(10H)=0FFH,(11H)=00H,(12H)=0FFH,(13H)=00H,写出每一步指令运行结果 MOV A,10H(A)= , ANL A,#01H(A)= , MOV A,11H(A)= , ORL A,#01H(A)= , MOV A,12H(A)= , XRL A,#01H(A)= , MOV A,13H(A)= , XRL A,#0AA(A)= ,
- 已知(10H)=5AH,(2EH)=1FH, (40H)=2EH,(60H)=3DH<br/>执行下列程序段后:MOV 20H,60H MOV R1,20H MOV A,40H XCH A,R1 XCH A,60H XCH A,@R1 MOV R0,#10H XCHD A,@R0 (A)=______ ,(10H)=______ ,(2EH)=______ ,(40H)=______ ,(60H)=______
