Note: Data should not be written to addresses 08H through 1FH.
When the PDN pin goes “L” to “H” upon power-up etc., the AK4620B will be ready for normal operation by the next
sequence. In this case, all control registers are set to default values and the AK4620B is in the reset state.
The clock mode should be changed after setting RSTAD bit and RSTDA bit to “0”. At that time, ADC outputs and DAC
outputs should be muted externally.

Control Register Setup Sequence
(1) Set the clock mode and the audio data interface mode.
(2) Cancel the reset state by setting RSTAD bit or RSTDA bit to “1”. Refer to Reset Contorl Register (01H).
(3) ADC output and DAC output should be muted externally until canceling each reset state.
PDN pin = “L” resets the registers to their default values.
