Tool/software:
(PCM1754-Q1) If the IC is powered off, the four pins SCK, BCK, LRCK, and DATA still have signal inputs.I would like to check if this would cause an abnormal situation in the IC.
Thank you very much for your help.

Hello Boxu,
Leaving the I2S on while the device is off, doesn't cause any issue. Once the power is restored, the initialization sequence requires 1024 system clocks from the time VCC > 3 V .
