When at "L", the AK4319A is in power-down mode and is held in reset.
The AK4319A should always be reset upon power-up.
When an external clock is input, this pin should be left floating.
The inverted XTI clock is output.
When this pin goes "H", soft mute cycle is initiated.
When returning "L", the output mute releases.
2's complement MSB-first data is input on this pin.
"L": MCLK=256fs,"H": MCLK=384fs
Must be left floating or tied to AVSS.
A crystal can be connected between this pin and XTO, or an external
CMOS clock can be input on XTI.
Normally connected to AVSS with a 0.1uF ceramic capacitor in parallel
witha 10uF electrolytic capacitor.
