3 The Audio Mixer is a on-chip functional module that allows mixing of two
4 audio streams into a single audio stream. Audio Mixer has two input serial
5 audio interfaces. These are driven by two Synchronous Audio interface
6 modules (SAI). Each input serial interface carries 8 audio channels in its
7 frame in TDM manner. Mixer mixes audio samples of corresponding channels
8 from two interfaces into a single sample. Before mixing, audio samples of
10 Audio Mixer is also a serial audio interface. Like input interfaces it has
12 interface of audio codec and also sent to the external pins along with the
13 receive path of normal audio SAI module for readback by the CPU.
