27 Multi-SSI : 6ch case, you can use stereo x 3 SSI
28 TDM-SSI : 6ch case, you can use TDM
185 But you can't use it if SSI was PIO mode.
186 In DMA mode, you can select not to use SSIU by using "no-busif" via SSI.
192 and these sounds will be merged SSIU/SSI.
211 * SSI (Serial Sound Interface)
217 Note: The system will drop non-SSI modules in PIO mode
