To clarify, you propose following definition of normal FSYNC polarity:
- for I2S/left/right justified - frame starts with falling FSYNC edge
- for DSP A/B - frame starts with rising edge of FSYNC edge (plus offset)
Yes.
- for AC97 my guess it is the same as DSP - frame starts with rising
FSYNC edge.
For AC'97 we don't support any kind of non-standard framing and would push back strongly against anyone who wants it but I guess yes.
