An external TTL clock should be input on this pin.
When at “L”, the AK4380 is in the power-down mode and is held in reset.
The AK4380 should always be reset upon power-up.
“L”: Normal Speed, “H”: Double Speed
“L”: Serial control mode, “H”: Parallel control mode
Normally connected to VSS with a 0.1 F ceramic capacitor in parallel with
a 10 F electrolytic cap.
“H”: Enable, “L”: Disable
When SDTI of both channels follow a total 8192 LRCK cycles with “0” input
data, this spin goes to “H”.
