Claim 3:
4. The system of claim 1, wherein the e-pen further comprising:
a write e-pen sensor electrode;
a third DSC operably coupled to the write e-pen sensor electrode, wherein, when enabled, the third DSC configured to:
drive a write e-pen signal having a third one or more characteristics that are different than the first one or more characteristics and the second one or more characteristics via a third single line coupling to the write e-pen sensor electrode and simultaneously sense, via the third single line, change of the write e-pen signal, wherein based on interaction of the e-pen with the touch sensor device, the write e-pen signal is coupled into the touch sensor electrode of the touch sensor device; and
process the change of the write e-pen signal to generate a third digital signal that is representative of a third electrical characteristic of the write e-pen sensor electrode.
