Claim 16:
17. The system of claim 14, wherein the first DSC further comprising:
a power source circuit operably coupled to the erasure e-pen sensor electrode of the e-pen via the first single line, wherein, when enabled, the power source circuit configured to provide the erasure e-pen signal that includes an analog signal via the first single line coupling to the erasure e-pen sensor electrode, and wherein the analog signal includes at least one of a DC (direct current) component or an oscillating component; and
a power source change detection circuit operably coupled to the power source circuit, wherein, when enabled, the power source change detection circuit is configured to:
detect an effect on the analog signal that is based on the first electrical characteristic of the erasure e-pen sensor electrode; and
generate the first digital signal that is representative of the first electrical characteristic of the erasure e-pen sensor electrode.
