The AK4384 must be reset once upon power-up.
10µF electrolytic cap.
An external TTL clock should be input on this pin.
When at “L”, the AK4384 is in the power-down mode and is held in reset. The
“L”: Manual Setting Mode, “H”: Auto Setting Mode
“L”: Serial control mode, “H”: Parallel control mode
Normally connected to VSS with a 0.1µF ceramic capacitor in parallel with a
“H”: Enable, “L”: Disable
