3.3.3.8 DEF_DRIFT_HOLD_TIME

When a sensor is in the detect state, the drifting on all other sensors is stopped. When the finger is removed (when the sensor goes out of detect state) drifting is started. "Drift Hold Time" defines the amount of time the drifting needs to be paused after removing the finger. This value is scaled by 200 ms. It is essential to pause the drift for couple of seconds, as there is a possibility that the finger is still around the sensors and causing some difference in signal and reference.
