mechanism, the two audio signals are converted into a single data queue. When the lrclk is high, the left-channel data is transmitted; when the lrclk is low, the right-channel data is transmitted. Compared with PCM, IIS is more suitable for stereo systems. For multi-channel systems, it is also possible to execute several data queues in parallel under the same bclk and lrclk conditions.3 ac97 InterfaceAC '97 (audi
