ASRC in TDM mode - clock edge

There is an ambiguity on the sampling edge for ARSC in Sharcs for TDM mode.

The datasheet for ADSP-21364 rev G p.34 shows a rising edge for sampling FS/SDATA, not specifying the mode.

The HRM for ADSP-2136x rev 2 p.402 shows a falling edge for sampling FS/SDATA in TDM mode, and rising for all other modes. The drawing is exactly the one from the AD1896 datasheet p.23.

 

Which one is good in TDM mode ?

Does this applies also to ADSP-214xx ?

 

Thanks,
