	*							CHANGE V0.0.3 hw: ppO2 sensor values
	*							CHANGE V0.0.4 hw: fix event bytes according to hwos_interface.odt dated 160610 in bitbucket hwOS

  ==============================================================================
              ##### Header #####
  ==============================================================================
  [..] SLogbookHeader
				The order has changed in comparsion to OSTC3 for perfect alignment
				with 16bit and 32bit. The header is 256kB as well.
				DO NOT rearrange anything but add new data to a second page
				beyond diveHeaderEnd. Use extraPagesWithData to indicate that there is
				data available that was not available in the OSTC3 256KB
				This data will be behind the diveHeaderEnd. DO NOT delete diveHeaderEnd.

	[..] SLogbookHeaderOSTC3
				is the format used by the OSTC3.
				logbook_getHeaderOSTC3() does the job using the global headers in logbook.c

	[..] SSmallHeader
				- is the format used by the OSTC3

	[..] Summary
				The header format is not perfect and might be optimized prior to
				releasing the diving computer. For now it is good to be compatible
				with PC software available for checking the content of the logbook
