*ARM Non-Secure Callable Region base address*

Type: ``hex``

Help
====

.. code-block:: none

    Start address of Non-Secure Callable section.

    Notes:
    - The default value (i.e. when the user does not configure
    the option explicitly) instructs the linker script to
    place the Non-Secure Callable section, automatically,
    inside the .text area.
    - Certain requirements/restrictions may apply regarding
    the size and the alignment of the starting address for
    a Non-Secure Callable section, depending on the available
    security attribution unit (SAU or IDAU) for a given SOC.
