On Page 1050 of IMCRT1010RM.pdf TCR2 

NOTE: Depending on the device, some Master Clock options might not be available. See the chip- specific information for the meaning of each option.

MSEL 

00b - Bus Clock selected.
01b - Master Clock (MCLK) 1 option selected.
10b - Master Clock (MCLK) 2 option selected.
11b - Master Clock (MCLK) 3 option selected.

Which option to use?

To select an external MCLK which option?

To select S/PDIF RX recovered MCLK as MCLK for the SAI which option?

Please help to clarify.

Many thanks.

Hi Emag,

You can see MCLK mux options in Figure 31-3. Audio subsystem clocking diagram. Additionally, you can use MCUXpresso Config Tools to configure this directly.
