已知(60H)=8H,(R0)=60H,(A)=7H,问执行指令 后,(60H)=7H
A: MOV R0,A
B: MOVX R0,A
C: DEC @R0
D: DEC R0
A: MOV R0,A
B: MOVX R0,A
C: DEC @R0
D: DEC R0
举一反三
- 假设(30H)=60H,(60H)=55H,则执行下列指令后,(A)=H,MOV R0,30HMOV A,@R0
- 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)=______
- 指令 MOV R0,20H 执行前 (R0)=30H, (20H)=38H,执行后(R0)=?
- 在执行下列指令后,A=(),R0=(),(60H)=()。MOV A,#45HMOV R0,#60HMOV @R0,AXCH A,R0
- 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
