Use a switch to control the lighting and extinguishing of LEP lamp

Use proteus Simulation software and
Programming software keil、 Joint debugging .
The procedure is as follows ：

	  			ORG 0000H 
	 MAIN: 	    MOV R0,#11111111B
	            MOV R1,#11111110B
	            MOV P2,#00FFH
	 LOOP:		MOV A,P2
			    JB ACC.0,MODE1
	            MOV A,R1
	            SJMP OUT
	MODE1:		MOV A,R0
	OUT:		MOV P0,A
				SJMP LOOP
				END

Proteus Simulation can work with KEIL Joint debugging of software .
