Power-Down & Reset Timing
Note 14. BICK rising edge must not occur at the same time as LRCK edge.
Note 15. SDTO2 output is fixed to “L”.
Note 16. This value is MCLK=512fs. Duty cycle is not guaranteed when MCLK=256fs/384fs.
Note 17. The AK5388 can be reset by bringing the PDN pin = “L”.
Note 18. This cycle is the number of LRCK rising edges from the PDN pin = “H”. The value is when the AK5388 is in
