[ADV7511W] Is sampling frequency of SPDIF updated automatically when we set register 0x0C[7] to "0"?

Hello,

I have a question about ADV7511W.

There is a following description about sampling frequency of SPDIF on Programming Guide P.40.
"In the case of SPDIF, the source of the sampling rate information is set in register 0x0C[7]."

 

Does this mean sampling frequency of SPDIF is updated automatically when we set register 0x0C[7] to "0"?

 

Also, there is a following description about register 0x0C[7] on Programming Guide P.71.
0x0c[7]
Select source of audio sampling frequency for pixel repeat and I2S mode 4
0 = use sampling frequency from I2S stream
1 = use sampling frequency from I2C register

 

About "0 = use sampling frequency from I2S stream", is this not "I2S stream" but SPDIF?
(Is this wrong?)

 

In case of I2S, I think user must set the sampling frequency by register 0x15
because there is a following description about I2S on Programming Guide P.40.
"For I2S, the sampling rate is determined by register 0x15.
.....Omission.....
With I2S, the sampling rate is always set by the user."

 

Thank you.
Best regards.
