请说明下列指令属于哪一种寻址方式?
MOV 23H,#30H ()
MOV 12H,A()
MOV R0,#23H()
MOV R7,12H()
MOV R1,#12H()
MOV A,@R0()
MOV 34H,@R1()
MOV 45H,34H()
MOV DPTR,#6712H()
MOV 12H,DPH()
MOV R0,A()
MOV A,@R0()
A 立即寻址 B 直接寻址 C 间接寻址 D 寄存器寻址
MOV 23H,#30H ()
MOV 12H,A()
MOV R0,#23H()
MOV R7,12H()
MOV R1,#12H()
MOV A,@R0()
MOV 34H,@R1()
MOV 45H,34H()
MOV DPTR,#6712H()
MOV 12H,DPH()
MOV R0,A()
MOV A,@R0()
A 立即寻址 B 直接寻址 C 间接寻址 D 寄存器寻址
举一反三
- 源操作数是寄存器寻址是( )。 A: MOV A, B: 12H C: MOV R7,12H D: MOV R0,A E: MOV 12H,C
- MOV @R0,35H属于哪一种寻址方式?
- 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
- 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
