a plurality of sets of drive-sense circuits, wherein each set of drive-sense circuits of the plurality of sets of drive-sense circuits includes a plurality of drive-sense circuits coupled to electrodes of a corresponding set of electrodes of the plurality of sets of electrodes, and wherein each set of drive-sense circuits is operable to generate a set of sensed signals indicating variations in capacitance associated with a proper subset of the plurality of cross points formed by the corresponding set of electrodes; and
a processing module that includes at least one memory that stores operational instructions and at least one processing circuit that executes the operational instructions to perform operations that include:
operating in a first mode during a first temporal period based on:
activating exactly one set of drive-sense circuits of the plurality of sets of drive-sense circuits to generate a corresponding one set of sensed signals during the first temporal period;
receiving the corresponding one set of sensed signals from the exactly one set of drive-sense circuits during the first temporal period; and
processing the corresponding one set of sensed signals to generate first proximal interaction data for the first temporal period; and
