*(No prompt -- not directly user assignable.)*

Type: ``bool``

Help

.. code-block:: none

    This option signifies the use of an ARMv7-M processor
    implementation, or the use of a backwards-compatible
    ARMv8-M processor implementation supporting the Main
    Extension.

    Notes:
    - A Processing Element (PE) with the Main Extension is also
    referred to as a Mainline Implementation.
    - ARMv7-M compatibility requires the Main Extension.

    From https://developer.arm.com/products/architecture/m-profile:
    The Main Extension provides backwards compatibility
    with ARMv7-M.
