*Use Read-Modify-Write command in flash\_write()*

Type: ``bool``

Help

.. code-block:: none

    Use the Read-Modify-Write command (opcode 0x58) instead of the default
    Main Memory Program without Built-In Erase (opcode 0x02). This allows
    writing of data without prior erasing of corresponding pages.
