Note 17. When the 1152fs, 512fs or 768fs /256fs or 384fs /128fs or 192fs are switched, the AK4495S/95
should be reset by the PDN pin or RSTN bit.
Note 18. BICK rising edge must not occur at the same time as LRCK edge.
Note 19. DSD data transmitting device must meet this time.
Note 20. Data must be held for sufficient time to bridge the 300 ns transition time of SCL.
Note 21. The AK4495S/95 can be reset by bringing the PDN pin to “L”.
