########################

*Ticker low latency mode*

Type: ``bool``

Help
====

.. code-block:: none

    This option enables legacy ticker scheduling which defers overlapping
    ticker node timeouts and thereby prevents ticker interrupts during
    radio RX/TX. Enabling this option disables the ticker priority- and
    'must expire' features.
