.. option:: CONFIG_ARC_STACK_PROTECTION

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

Type: ``bool``

Help
====

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.
