Notes:
Data must not be written into addresses from 05H to 1FH.
When the PDN pin goes to “L”, the registers are initialized to their default values.
When RSTN bit is set to “0”, only the internal timing is reset, and the registers are not initialized to their default
values.
When the state of the PSN pin is changed, the AK4392 should be reset by the PDN pin.
