Type: ``bool``

.. code-block:: none

    This option enables either:
    - The ARC stack checking, or
    - the MPU-based stack guard
    to cause a system fatal error
    if the bounds of the current process stack are overflowed.
    The two stack guard options are mutually exclusive. The
    selection of the ARC stack checking is
    prioritized over the MPU-based stack guard.
