.. title:: ARC_USE_UNALIGNED_MEM_ACCESS

.. option:: CONFIG_ARC_USE_UNALIGNED_MEM_ACCESS

*Enable unaligned access in HW*

Type: ``bool``

Help
====

ARC EM cores w/o secure shield 2+2 mode support might be configured
to support unaligned memory access which is then disabled by default.
Enable unaligned access in hardware and make software to use it.
