Audio Serial Data Input Pin
2's complement MSB-first data is input on this pin.
Power-Down Mode Pin
When at "L", the AK4319A is in power-down mode and is held in reset.
The AK4319A should always be reset upon power-up.
Master Clock Input Pin
A crystal can be connected between this pin and XTO, or an external
CMOS clock can be input on XTI.
Crystal Oscillator Output Pin
When an external clock is input, this pin should be left floating.
Clock Output Pin
The inverted XTI clock is output.
Soft Mute Pin
When this pin goes "H", soft mute cycle is initiated.
When returning "L", the output mute releases.
