6. JP1 (CLKS) : Selection of external master clock input and crystal oscillator input .
XTAL : Select crystal oscillator input . <Default>
MCKI : Select external master clock input.
7. JP10 (XTE) : Selection of clock source for the MCKI/XTI pin.
OPEN : Select X’tal as the clock source. (XTE pin = “H”) <Default>
SHORT : Select external clock as the clock source (XTE pin = “L”)
8. JP16 (EXT) : Selection of external clock input impedance.
OPEN : External clock input impedance is High impedance.
SHORT : External clock input impedance is 51Ω.<Default>
9. JP9 (CKM) : Selection of reference X’tal frequency.

„ The function of the toggle SW
[SW2] (LMUTEN): Left channel mute switch. Keep pressing the button if mute is needed.
[SW3] (RMUTEN): Right channel mute switch. Keep pressing the button if mute is needed.
„ Indication for LED
[D1] (SUSN): Monitor SUSN pin of the AK5374. LED turns off when the AK5374 is on suspend state.
