In the “synchronous” mode, the sensor (slave) starts to transfer a complete data frame
only after a low pulse is forced by the master on the OUT pin. This means that the data
line is bidirectional - an open drain output of the microcontroller (master) sends the
trigger pulse. The sensor then initiates a sync pulse and starts to calculate the new
output data value. After the synchronization period, the data follows in form of a standard
SENT frame, starting with the status, data and CRC nibbles. At the end, an end pulse
allows the CRC nibble decoding and indicates that the data line is idle again. The timing

The low time duration of the master can be used to select the magnetic range of the
sensor in SPC dynamic range selection mode.
