Abstract

An integrated circuit that communicates with a host device via audio channels includes an interfacing circuit that receives and transmits analog signals on the audio channels. Such audio channels are designed for audio speakers and microphones and the interfacing circuit transmits digital data based on the received analog signals. The integrated circuit includes a processing device that is electrically coupled to the interfacing circuit. The processing device receives the digital data from the interfacing circuit and adjusts at least one parameter of the interfacing circuit based on the received digital data. The interfacing circuit receives the digital data from the processing device and transmits analog signals on at least one of the audio channels based on the at least one adjusted parameter.
