假定A=23H,(R0)=16H,(16H)=34H,执行完以下指令后,则A的内容为,16H地址上的内容为
ANL A, #17H
ORL 16H, A
XRL A, @R0
CPL A
ANL A, #17H
ORL 16H, A
XRL A, @R0
CPL A
举一反三
- 假定A=38H,(R0)=17H,(17H)=34H,执行以下指令: ANL A,#17H ORL 17H,A XRL A,@R0 CPL A 后,A的内容为
- 假定(A)=83H,(R0)=17H,(17H)=34H,执行以下程序段 ANL A,#17H ORL 17H,A XRL A,@R0 CPL A 后,A的内容为( )
- 【填空题】假定(A)=83H,(R0)=17H,(17H)=34H,执行以下指令后,(A)=____。 ANL A,#17H ORL 17H,A XRL A,@R0 CPL A
- 假定A=83H,R0=17H,(17H)=34H,执行以下指令: ANL A, #17H ORL A, @R0 CPL A
- 假定(A)=83H,(R0)=17H,(17H)=43H,执行以下指令后,(A)=()。 ANL A,#17H; ORL 17H,A XRL A,@R0 CPL A
