About IRQ level

Hi
i am using dw10001,Accidentally, iqr pin will always be set high.Irq pin does not take pulldown resistance.The value in register 0x0F is cleared, but iqr pin is still high level.What’s the matter, please?
MCU USES nrf52832, the interrupt pin configuration is as follows

ret_code_t err_code;

err_code = nrf_drv_gpiote_init();
//APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_LOTOHI(true);
in_config.pull = NRF_GPIO_PIN_PULLDOWN;

err_code = nrf_drv_gpiote_in_init(DW_IrqPin, &in_config, CDriver_irq_handler);
APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_event_enable(DW_IrqPin, true);

thanks
