*Edge interrupts using SENSE*

Type: ``bool``

Help
====

.. code-block:: none

    Enable GPIO edge interrupts implementation using GPIO SENSE, which is
    a level interrupt mechanism. Conversion from level to edge interrupts
    notification happens in GPIO driver, so it is transparent to GPIO
    consumers after switching from GPIOTE mechanism.

    Use this option as an alternative to GPIOTE event mechanism. According
    to product specifications and erratas to some nRF MCUs, using GPIOTE
    results in increased current consumption in System ON Idle and in
    conjunction with SPI/TWI peripherals. Selecting this option allows to
    reduce current for those cases.

    Using this option additionally allows detecting state changes of pins
    configured as output, which might be handy for some applications.
