Toggle switch

[SW3] (PDN):

Switch for power down reset of AK4683 (U1). Keep “H” during operation of AK4683 (U1).

Power down reset of AK4683 will be done by setting SW3 (PDN) to “L” once, after power on.

[SW1] (AK4114-PDN): Switch for power down reset of AK4114 (U5). Keep “H” during operation of AK4114 (U5).

Power down reset of AK4114 (U5) will be done by setting SW1 to “L” once, after power on.

LED indication

[LE1] (INT):

LED for output of AK4683 (U1): INT. It turns on when output of AK4683 (U1): INT is “H”.

[LED1] (ERF):

LED for output of AK4114 (U5): INT0.It turns on when output of AK4114 (U5): INT0 is “H”.
