Constant latency hotfix module
##############################

Enable the constant latency hotfix module to use a device configuration with constant latency interrupts.
This reduces the interrupt propagation time, but increases the power consumption.

Module events
*************

.. include:: ../../../../../../applications/nrf_desktop/doc/event_propagation.rst
    :start-after: table_constlat_start
    :end-before: table_constlat_end

.. note::

Configuration
*************

To enable the module, use the :option:`CONFIG_DESKTOP_CONSTLAT_ENABLE` Kconfig option.

You can set the :option:`CONFIG_DESKTOP_CONSTLAT_DISABLE_ON_STANDBY` option to disable the constant latency interrupts when the device switches to the low power mode (on :c:struct:`power_down_event`).
The constant latency interrupts are re-enabled on a :c:struct:`wake_up_event`.
