Are i.MX6 REF_CLK_24M REF_CLK_32K bypassed clock from external x'tals?

Hi community,

 

I have a questions about i.MX6 XTALOSC.

I want to measure the waveform of external x'tals (24MHz, 32kHz).

Then, to do accurate measurement, I consider using output from i.MX6 for measurement.

At first time, I thought I can use CLKOx, but I stopped it because the output ckil_sync_clk_root is not original and synchronized clock by IPG_CLK as per page. 814 in the RM.

So now, I consider using REF_CLK_24M & REF_CLK_32K.

I guess, these output are bypassed clock from external 24MHz and 32kHz.

Is this correct?
