Notes: 18. When the normal/double/quad speed modes are switched, AK4394 should be reset by PDN pin or RSTN bit.
19. BICK rising edge must not occur at the same time as LRCK edge.
20. The AK4394 can be reset by bringing PDN “L” to “H”.
When the states of CKS2-0 or DFS1-0 change, the AK4394 should be reset by PDN pin or RSTN bit.
