For the autonomous QTouch sensor, specifies how far a sensor’s signal must move in a positive direction from the reference in
order to cause a recalibration.
For the autonomous QTouch sensor, specifies how often a positive drift compensation should be performed. When this field is
zero, positive drift compensation will never be performed. When this field is non-zero, the positive drift compensation time
interval is given by the following formula:
Tpdrift = PDRIFT * 65536 * (sample clock period)
For the autonomous QTouch sensor, specifies how often a negative drift compensation should be performed. When this field is
zero, negative drift compensation will never be performed. When this field is non-zero, the negative drift compensation time
interval is given by the following formula:
Tndrift = NDRIFT * 65536 * (sample clock period)
