*Use Deep Power-Down mode when flash is not being accessed.*

Type: ``bool``

Help
====

.. code-block:: none

    Where supported deep power-down mode can reduce current draw
    to as little as 0.1% of standby current.  However it takes
    some milliseconds to enter and exit from this mode.

    Select this option for applications where device power
    management is not enabled, the flash remains inactive for
    long periods, and when used the impact of waiting for mode
    enter and exit delays is acceptable.
