1. A method of operation by an apparatus interfaced with a touch sensor, the method comprising:
determining that a sensing line of the touch sensor is not operative and that respective sensing lines running adjacent to the inoperative sensing line are operative, the touch sensor having a plurality of sensing lines arranged for detecting touch inputs to a touch surface of the touch sensor;
adjusting a touch-detection sensitivity used for evaluating sensing signals output from the adjacent sensing lines, to provide touch detection within a region of the touch surface that corresponds to the inoperative sensing line and is bounded by the adjacent sensing lines;
adjusting one or both of an excitation frequency or an excitation voltage used to produce the sensing signals, in conjunction with adjusting the touch-detection sensitivity; and
evaluating the sensing signals for touch-detection according to the adjusted touch-detection sensitivity.
