.. option:: CONFIG_ENTROPY_STM32_RNG

*STM32 RNG driver*

Type: ``bool``

Help
====

.. code-block:: none

    This option enables the RNG processor, which is a entropy number
    generator, based on a continuous analog noise, that provides
    a entropy 32-bit value to the host when read. It is available for
    F4 (except STM32F401 & STM32F411), L4, F7, H7 and G4 series.
