Triaxis^ Position Sensor Assembly feat. SENT
13.4. 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 8 “Timing specifications”.
13.5. Field sensing (ADC conversions) and the frame Synchro pulse
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.
