UART Receice Data nrf52840

[MainOFF]

Hi everyone! I have probelem with receice data over UART. In the other MCU use core ARM as : STM32, NXP... when a byte is recieved, MCU has flag to notify. That is "interrupt". But in the NRF52, I can't see it. I always use "polling" mechanism to receive data. How can I use "interrupt" to receive data? thanks!!!

Thanks for your response. Can I use it as :

void uart_callback_handle(app_uart_evt_t * p_event)
{
    if (p_event->evt_type == APP_UART_COMMUNICATION_ERROR)
    {
        APP_ERROR_HANDLER(p_event->data.error_communication);
    }
     if (p_event->evt_type == APP_UART_FIFO_ERROR)
    {
        APP_ERROR_HANDLER(p_event->data.error_code);
    }
		if( p_event->evt_type == APP_UART_DATA_READY)
		{
			while(app_uart_get(&data)!=NRF_SUCCESS) {};
			data_arr[index]=data;
			index++;
				if(index==10)
				{index=0;xong=1;}
		}		 
}

Yes, that should work fine.
