Table. Serial Message Sequence

The first part (positions 1 to 8) provides the Error Code and the Sensor ID alternatively.

The second part (positions 9 to 18) is optional as a whole enabled with EEPROM bit

EE_ExtendedSequence.

This second part consists of the error code (5 occurrences), 4 User-defined messages (ID and data) and

the SENT revision.
