Abstract
Including control data in a serial audio stream is presented herein. A device can include a clock component that is configured to send, via a clock pin of the device, a bit clock signal directed to a slave device. A frame component can send, via a frame pin of the device, a frame clock signal directed to the slave device. A control component can receive, via a data pin of the device during a first portion of a phase of a period of the frame clock signal, slave data from the slave device on a bit-by-bit basis based on the bit clock signal according to an integrated interchip sound (I2S) based protocol; and send, via the data pin during a second portion of the phase after the first portion, a set of control bits directed to the slave device on the bit-by-bit basis based on the bit clock signal.
