  ==============================================================================
                        ##### Version Changes #####
  ==============================================================================
	160217 V0.0.3 pStateUsed->decolistXXXXX.tickstamp = HAL_GetTick(); added
	150627 V0.0.2 
	
  ==============================================================================
                        ##### How to use #####
  ==============================================================================

  ==============================================================================
            ##### Button, Set Time, Clear Deco etc Request #####
  ==============================================================================
	was updated (151207) for buttons and clear deco at the moment only
	using requestNecessary and checking in DataEX_copy_to_LifeData()
	Hence if there is no confirm from the smallCPU on the data after the request
	the request will be send again.
	
	==============================================================================
                        ##### Device Data #####
  ==============================================================================
	
	main CPU always sends the device data info that it has at the moment

		on start it is INT32_MIN, INT32_MAX and 0 
		as initialized  in data_central.c variable declaration
	
	second small CPU gets request to send its device data
		
		on receiption the data is merged with the data in externLogbookFlash,
		stored on the externLogbookFlash and from now on send to small CPU

  ==============================================================================
            ##### Magnet Reset #####
  ==============================================================================
