Abstract
A touch sensor panel configured to minimize the effect on touch or proximity event detection caused by a common mode noise event. The touch sensor panel includes circuitry that works to minimize the amount of time that the touch sensor panel is unable to accurately sense touch and proximity events due to a common mode noise event. The touch sensor panel can also re-acquire data that was collected during the time that the sensor panel was unable to accurately detect touch and proximity events, when a common mode noise event is detected.
