1. An apparatus for scanning a sensor panel for events, comprising: driver logic configured for generating one or more input signals; and channel scan logic configured for disabling touch detection after a first predetermined amount of time elapses without any events being detected on the sensor panel, enabling touch detection, controlling the driver logic to drive at least one row in the sensor panel with the one or more input signals, and acquiring an image of the sensor panel upon expiration of a second predetermined amount of time, and determining if any events are detected on the sensor panel; wherein the acquiring of the image includes measuring a capacitance of one or more sensors in the sensor panel.
