Activated ringbuffer for settings: In previous versions the settings have always been writte to the ring start address causing additional ~200ms for sector erase. The settings are now continously written (~8ms). At shutdown the settings are written to ring start for compability reasons. In case of a reset the SW will scan the ringbuffer for the latest available block and restore it.
