Abstract
A communication system of the present disclosure includes a communication device that is communicatively coupled to a peripheral device. The peripheral device selects a selectable impedance from among multiple selectable impedances to communicate peripheral device information to the communication device. The communication device operates in an acquisition mode of operation to determine the selectable impedance to recover the peripheral device information. Optionally, the communication device can transition to a response mode of operation to respond to the peripheral device information.
