            The flash chips used in Atmel AT91FR40162 microcontrollers have a silicon bug
            that causes erase operations to be unreliable unless any data to be erased is
            cleared first, see http://www.atmel.com/dyn/resources/prod_documents/doc6076.pdf.
            Selecting this option enables that workaround. Of course, erase operations will be
            slower then."
