Abstract
A processing system for a capacitive input device comprises sensor circuitry and control logic. The sensor circuitry is configured to be communicatively coupled with sensor electrodes of the capacitive input device. The control logic is configured to operate the capacitive input device in a first mode comprising interference sensing at a first level and input object sensing. The control logic is also configured to operate the capacitive input device in a second mode instead of in the first mode in response to: interference measured in the first mode meeting an interference condition; and a determination that input is in a sensing region of the capacitive input device. While operating in the second mode, interference sensing with the capacitive input device is either not performed or else is performed at a second level that is lower in fidelity than the first level.
