Triaxis^® Position Sensor IC feat. SENT
The second part (positions 24 to 40) is optional as a whole enabled with EEPROM bit
EE_ExtendedSequence.
This second part consists of the error code (8 occurences), 8 OEM -defined Code
The temperature can be derived from SENT ID 23, TEMP sensor, with the following equation:
SENT@ ID 23 = 8 * (T[C] – 35[C]) + 865 lsb12
The accuracy of the actual Temperature is = ± 10 DegC.

14.3.3.1. Error Code Rate
The Error Code are on purpose transmitted every second message, to maximize the rate, which equals
then 36 SENT frames.
14.3.4. Serial Message Error Code
The list of error and status messages transmitted in the 12-bit Enhanced Serial Message data field when
Enhance Serial Message ID is $01 is given in the following Table.

In case multiple errors occur, then the resulting 12 bit enhanced serial message data will be the OR-operation of the
individual data values. Example $809 = GainOOS + ADCsatura
