Abstract:
A voltage supply circuitry is capable of coupling to wired audio headset circuitry and configurable to operate in a first mode, wherein the voltage supply circuitry provides a voltage supply to the wired audio headset functionality circuitry. The voltage supply circuitry is further capable of coupling to visual indication circuitry and further configurable to operate in a second mode, wherein the voltage supply circuitry provides a voltage supply to the visual indication circuitry.
