Abstract
Sensor circuitry is configured to perform, for a sensing frame, mutual capacitive sensing to obtain mutual capacitive measurements, and perform, for the sensing frame, first self-capacitive sensing to obtain first self-capacitive measurements, and perform second self-capacitive sensing to obtain a second self-capacitive measurements. Processing circuitry is connected to the sensor circuitry and is configured to detect an inconsistency between the mutual capacitive measurements and the first self-capacitive measurements, and halt, in response to detecting the inconsistency, a second sensing frame to trigger performing the second self-capacitive sensing. The second sensing frame is subsequent to the first sensing frame. The processing circuitry is further configured to determine intermittent interference using the first self-capacitive measurements and the second self-capacitive measurements.
