Note 18. When the 1024fs, 512fs or 768fs /256fs or 384fs /128fs or 192fs are switched, the AK5556
should be reset by the PDN pin or RSTN bit.
Note 20. tDDD is defined from a falling edge of DCLK “↓” to a DSDOL/R edge when DCKB bit = “0” and it
is defined from a rising edge of DCLK “↑” to a DSDOL/R edge when DCKB bit = “1”.
