When at "L", the AK4317 is in power-down mode and is held in reset.
The AK4317 should always be reset upon power-up.
When this pin goes "H", soft mute cycle is initiated.
When returning "L", the output mute releases.
The differential Voltage between this pin and AVSS set the analog output
2's complement MSB-first data is input on this pin.
Must be tied to "H" or "L" if this pin is not used.
