1. An apparatus, comprising: a plurality of capacitive sense elements; a first capacitance sensor and a second capacitance sensor; and a switch circuit configured to couple the plurality of capacitive sense elements to the first and second capacitance sensors in different modes, wherein the switch circuit is configured to couple the first capacitance sensor to a first group of two or more of the plurality of capacitive sense elements in a first mode, wherein the switch circuit is configured to couple the second capacitance sensor to a second group of two or more of the plurality of capacitive sense elements, and wherein the switch circuit is configured to couple at least one of the first or second capacitance sensors to individual ones of the two or more of the plurality of capacitive sense elements in one of the first or second groups in a second mode.
