1. A touch sensor device comprising:
a first touch sensor system that includes:
a first plurality of electrodes including a first electrode;
a first plurality of drive-sense circuits (DSCs) including a first DSC, wherein the first plurality of DSCs operably coupled to the first plurality of electrodes; and
the first DSC operably coupled to the first electrode, wherein, when enabled, the first DSC is configured to:
drive a first signal via a first single line coupling to the first electrode and simultaneously sense, via the first single line, change of the first signal that is based on an electrical characteristic of the first electrode; and
process the first signal to generate a first digital signal that is representative of the electrical characteristic of the first electrode; and
a second touch sensor system that includes a second plurality of electrodes including a second electrode and a second plurality of DSCs including a second DSC, wherein the second touch sensor system is configured to service a cross-section of the touch sensor device that is also serviced by the first touch sensor system and is also configured to generate a second digital signal that is representative of an electrical characteristic of the second electrode of the second plurality of electrodes, wherein the first electrode is implemented in a first direction, and the second electrode is implemented in a second direction;
memory that stores operational instructions; and
one or more processing modules operably coupled to the first DSC, the second DSC, and to the memory, wherein the one or more processing modules, when enabled, configured to execute the operational instructions to:
coordinate operation of the first touch sensor system and the second touch sensor system including to:
operate the first touch sensor system without operating the second touch sensor system at a first time; and
operate the second touch sensor system without operating the first touch sensor system at a second time.
