###############################

*ARC exception handling stack size*

Type: ``int``

Help
====

.. code-block:: none

    Size in bytes of exception handling stack which is at the top of
    interrupt stack to get smaller memory footprint because exception
    is not frequent. To reduce the impact on interrupt handling,
    especially nested interrupt, it cannot be too large.

Direct dependencies
===================

\ :kconfig:`ARC <CONFIG_ARC>`

*(Includes any dependencies from ifs and menus.)*

Defaults
========

- 768 if !\ :kconfig:`64BIT <CONFIG_64BIT>`
- 2048 if \ :kconfig:`64BIT <CONFIG_64BIT>`
