Triaxis^® Position Sensor IC feat. SENT
14.4. Start-up
During the chip initialization, the output remains high until the circuit emits four initialization frames (all 6
data nibble zero). The fifth frame is not an initialization frame but a valid frame containing a measured
angle. See also section 9 “Timing specifications”. The first four frames conform to the SENT specification
and include a valid CRC.
14.5. Field sensing (A2D conversions) and the frame Synchro pulse
By default setting of the Timer period and Filter =1, the digital angle (fast channel payload) results of the
average of two angles.
These angles are themselves computed from 4 ADCs values.
The time between the ADCs and the frame synchro pulse is constant.
As a result, the phase delay between the magnetic field angle and the SENT synchro pulse is constant,
allowing filtering at the ECU side.
