A capacitive touch sensor includes horizontal lines vertical lines. Switching circuitry is coupled to the horizontal and vertical lines of the capacitive touch sensor. The switching circuitry is operable in a first mode to configure the horizontal lines as receive lines and the vertical lines as transmit lines for making a cross-capacitance measurement. In one implementation, the switching circuit is further operable in a second mode to configure the horizontal lines as transmit lines and the vertical lines as receive lines for making an additional cross-capacitance measurement. In another implementation, the switching circuit is further operable in a second mode to configure the vertical lines for making a self capacitance measurement. The various capacitance measurements from the first and second modes are algorithmically combined to obtain a total capacitance measurement having a reduced noise component.
