Register Definitions
For addresses from 05H to 1FH, data must not be written.
When PDN pin goes to “L”, the registers are initialized to their default values.
When RSTN bit goes to “0”, the only internal timing is reset and the registers are not initialized to their default values.
When the state of P/S pin is changed, the AK4396 should be reset by PDN pin.

Default
When the states of DFS1-0 bits change, the AK4396 should be reset by PDN pin or RSTN bit.
Initial value is “010” (Mode 2: 24bit MSB justified).
When ACKS bit = “1”, MCLK frequency and the sampling frequency are detected automatically.
