.. autoapi-nested-parse::

   Non-volatile memory

   The `nvm` module allows you to store whatever raw bytes you wish in a
   reserved section non-volatile memory.

   Note that this module can't be imported and used directly. The sole
   instance of :class:`ByteArray` is available at
   :attr:`microcontroller.nvm`.

.. py:class:: ByteArray

   Presents a stretch of non-volatile memory as a bytearray.

   Non-volatile memory is available as a byte array that persists over reloads
   and power cycles. Each assignment causes an erase and write cycle so its recommended to assign
   all values to change at once.

   Usage::

      import microcontroller
      microcontroller.nvm[0:3] = b"\xcc\x10\x00"

   Not currently dynamically supported. Access the sole instance through `microcontroller.nvm`.

   .. py:method:: __bool__() -> bool


   .. py:method:: __len__() -> int

      Return the length. This is used by (`len`)


   .. py:method:: __getitem__(index: slice) -> bytearray
               __getitem__(index: int) -> int

      Returns the value at the given index.


   .. py:method:: __setitem__(index: slice, value: _typing.ReadableBuffer) -> None
               __setitem__(index: int, value: int) -> None

      Set the value at the given index.
