Hi all,

       In my application I am using INT1 as -ve edge trigger interrupt
( PINSEL0_bit.P0_3 = 0x3).I also need to check the status of the same 
pin by configuring it as a GPIO( PINSEL0_bit.P0_3 = 0x0).
       But when i switching between GPIO & INT1 by using PINSEL ,I am 
getting INT1 interrupt (unnecessary interrupt).
       What may be the reason for it & how should i overcome it.  
     
Thanks & Regards,
