i.MX6 ASRC_ASRCTR setting.

Hi community,

I have a questions about i.MX6 ASRC_ASRCTR setting.

Please see chapter 15.7.1 in IMX6SDLRM Rev.1.

I understand pair A will automatic update when ATSA bit is 1, and update manually by USRA and IDRA bit when ATSA bit is 0.

Then, how about when the following setting?

Pair A will automatic update? or ASRC internal measured ratio will be used?

ATSA = 1

USRA = 1

IDRA = 0

Best Regards,

Satoshi Shimoda

Pair A will automatic update, based on ASRC internal measured ratio.

Hi Yuri,

According to your reply, ATSA setting and {USRA, IDRA} setting are applied at the same time.

Then, how about {ATSA, USRA, IDRA} = {1,0,0}.

I guess USRA & IDRA is ignored and "Pair A will automatic update its pre-processing and post-processing options based on the frequencies it detected".

Is this correct?
