Note 34. This value is SRC block only. It is the time from a rising edge of input LRCK after data is input to a
rising edge of output LRCK just before the data is output when there is no phase difference
between input and output LRCK.
Note 35. In the case of SRCFAUD bit = “1”
Note 36. In the case of SRCFAUD bit = “0”
