About ASI master clock of MX6UL

Dear all,


I want to use SAI of i.MX6UL.


I refer to Chapter 43 of RM.
- Chapter 43 Synchronous Audio Interface (SAI)


I have some questions.


I understand the Master Clock of SAI is generated by SAIx_CLK_ROOT.
Is SAIx_CLK_ROOT connected directly with Master Clock of SAIx?


In MCLK Select field of I2Sx_TCR2 register, audio Master Clock option can be chosen.
However, I cannot find the explanation about these options.

Would you tell me the point where this is explained?


In MCLK Select of the I2Sx_RCR2 register, would you tell me the concrete clock name of "00:Bus Clock selected"?


May I have advice?


Best Regards,
