Master/Slave Mode Change
MSA and MSB bits control the master/slave mode of PORTA and PORTB respectively. The “1” is for master mode,
“0” is for slave mode. The AK4683 is slave mode at power-down (PDN pin = “L”). To change to the master mode,
write “1” to MSA/MSB bit. The ACKSAI, ACKSAO and ACKSB bits are ignored in master mode. Until when writing
“1” to MSA/MSB bit, the ILRCKA, OLRCKA, BICKA, LRCKB and BICKB pin are input pins. Pull-up(or down)
resistor with around 100kohm is required to prevent the floating of these input pins.

Table 5. Select Master/Salve Mode
Note: When PORTA and PORTB operate synchronously, PORTB must not be the Master Mode. In that case the
PORTA must be the Master Mode, or both PORTA and PORTB must be the Slave Mode with supplying the
same BICK and LRCK.

Other Detection Function
The FUNC1-0 bit selects the function of VOUT / DZF / OVF pin.

Table 6. Detection Function Control
1. Overflow Detection
The AK4683 has overflow detect function for analog input. OVF pin goes to “H” if analog input of Lch or Rch
overflows (more than -0.3dBFS). OVF output for overflowed analog input has the same group delay as ADC (GD =
16/fs = 333
μ
s @fs=48kHz). OVF pin is “L” for 522/fs (=10.9ms @fs=48kHz) after PDN = “
↑
”, and then overflow
detection is enabled. The overflow detection is applied to the data between the digital HPF and the DATT.
