button1 GPIOTE interrupt enable for NRF52840_PCA10056

Hello,
I want to enable GPIOTE interrupt for for Button1. For that I write

void GPIOTE_IRQHandler(void *arg)
{
 
  if(NRF_GPIOTE->EVENTS_IN[0]!=0)
  {
    NRF_GPIOTE->EVENTS_IN[0]=0;

    NRF_P0->OUT ^= (1<<16);

  }
}

void gpio_init(void)
{


  NRF_P0->DIR |= 0x0001E000;           // for LEDs
  NRF_P0->OUTSET |= 0x0001E000;   // for LEDs

 

  NRF_P0->PIN_CNF[11]=0x0000000C;   // for making P0.11 as input

  NRF_GPIOTE->INTENSET |= 0x00000001;                         
  NRF_GPIOTE->CONFIG[0] |= 0x00000001 | (11<<8) | (2<<16);

  NVIC_EnableIRQ(GPIOTE_IRQn);
}

I am able to compile code successfully & as per my understanding after pressing Button1,
Led4 should toggle on every click.

But I think interrupt is not get executed.


Could anybody help me to solve this issue ?


How to rewrite logic as per it ? how to modify prj.conf ?


Thank You!!
