Drenesas,rsnd.txt1 Renesas R-Car sound
7 Renesas R-Car and RZ/G sound is constructed from below modules
11 - SRC : Sampling Rate Converter
12 - CMD
13 - CTU : Channel Transfer Unit
14 - MIX : Mixer
15 - DVC : Digital Volume and Mute Function
16 SSIU : Serial Sound Interface Unit
25 Multi channel is supported by Multi-SSI, or TDM-SSI.
27 Multi-SSI : 6ch case, you can use stereo x 3 SSI
