        description   "
            The driver will implement flash block locking when this
            option is enabled. Note that the device implements sector
            locking, not block locking, where sectors are bigger than
            blocks. So the sector which contains the block will be
            locked/unlocked

            WARNING: The errata says that these lock bits only have 
            a life of 100 cycles for the AT91SAM7S devices."
