I'm trying to use IOC (interr. on change) in 628, here is the code which works well on simmulator but not on hardware, what I want to do is that LED # 1 lights continiously as power is switched on and as interrupt occur (RB4 goes HIGH ) LED # 1 gets off and LED # 2 lights on and this remains so untill interrupt is not removed.
But, what is actually happening is that as interr. occur (RB4 goes high) LED #1 turns off but, LED # 2 doesn't lights up, can't understand whats wrong, please help !

	list p=16f628
		#include<p16f628.inc>
		__CONFIG  _MCLRE_ON & _CP_OFF & _WDT_OFF & _INTRC_OSC_NOCLKOUT
		ERRORLEVEL   -302
		cblock	0x20
			temp 
			temp_s      
  		endc

Sorry to bother my bread board is damaged the ckt works good on the other one.
