Development bugfix: Low battery warning was interpretated as marker:
The previous version checked event bit 1 and 2 and returned a marker in case both were set. The indication for a battery low warning is that the 3 LSBit of the event byte are set => not intended marker in case of low battery situation. To fix this an additional check for bit0 has been added.
