Abstract
According to an embodiment, a method for a touch scan is proposed. The method includes operating a device in first and second modes corresponding to the device, respectively, being wirelessly and not wirelessly charged. In each mode for each frame, the method includes dividing a frequency range corresponding to a touch-sensing technology into M or N positive integer numbers of equal and sequential frequency intervals, where N is greater than M. In the first mode, the method includes determining a first frequency interval of the M frequency intervals with the least noise and performing the touch scan using a first frequency within the first frequency interval. In the second mode for each frame, the method includes determining a second frequency interval of the N frequency intervals with the least noise and performing the touch scan using a second frequency within the second frequency interval.
