*Reg Pair ACCL:ACCH (FPU and/or MPY > 6)*

Type: ``bool``

Help
====

.. code-block:: none

    Depending on the configuration, CPU can contain accumulator reg-pair
    (also referred to as r58:r59). These can also be used by gcc as GPR so
    kernel needs to save/restore per process

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

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

Defaults
========

- y if \ :kconfig:`CPU_HS3X <CONFIG_CPU_HS3X>`
- y if \ :kconfig:`FPU <CONFIG_FPU>`
