   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`.

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


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

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


   .. method:: __getitem__(self, index: slice) -> bytearray


   .. method:: __setitem__(self, index: slice, value: ReadableBuffer) -> None
