16.10.4. Data Structure
The DATA could be a valid angle/field component or an error condition.
DATA: Angle/ Field Component A[15:0] with (Span)/2
DATA: Error
16.10.5. Angle Calculation
All communication timing is independent (asynchronous) of the angle data processing. The angle is
calculated continuously by the Slave:
The last angle calculated is hold to be read by the Master at any time. Only valid angles are transferred by
the Slave, because any internal failure of the Slave will lead to a soft reset.
16.10.6. Error Handling
In case of any errors listed in section 16.10.4, the Serial protocol will be initialized and the error condition
can be read by the master.
In case of any other errors (ROM CRC error, EEPROM CRC error, RAM check error, intelligent watchdog
error…) the Slave’s serial protocol is not initialized. The MOSI/MISO pin will stay Hi-impedant (no error
frames are sent).

ADC Failure
ADC Saturation (Electrical failure or field too strong)
The gain code is strictly less than EE_GAINMIN
The gain code is strictly greater than EE_GAINMAX
Goes high when the fast norm (the max of absolute x,y,z) is
below 30%
The norm (Square root) is strictly less than EE_FIELDLOW
The norm (Square root) is strictly greater than
EE_FIELDHIGH
Analog Chain Rough Offset Compensation: Clipping
The angle ALPHA lies in the deadzone
The angle BETA lies in the deadzone
