If you are using nRF5 SDK, then take look at the pin_change_int example.

For low-to-high sense, use GPIOTE_CONFIG_IN_SENSE_LOTOHI

    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(PIN_IN, &in_config, in_pin_handler);
    APP_ERROR_CHECK(err_code);

[quote userid="90016" url="~/f/nordic-q-a/62822/how-to-set-the-gpio-as-input-and-high-low-pin"]set the pin P0.2 low as analog input and p0.3 high as analog input[/quote]

What do you mean by that?

Do you want an analogue input with pull-up/down?

Or what?

Please explain further.
