Notes:
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 AK4397 should be reset by PDN pin.

RSTN: Internal timing reset
0: Reset. All registers are not initialized.
1: Normal Operation (default)
“0” resets the internal timing circuits. The register value will not be initialized.
DIF2-0: Audio data interface modes (Table 11)
Initial value is “010” (Mode 2: 24bit MSB justified).
ACKS: Master Clock Frequency Auto Setting Mode Enable (PCM only)
0: Disable : Manual Setting Mode (default)
1: Enable : Auto Setting Mode
When ACKS bit = “1”, MCLK frequency and the sampling frequency are detected automatically.
