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 6. Detection Function Control
1. Overflow Detection
The AK4683 has overflow detect function for analog input. Overflow detect function is enable if OVFE bit is set to “1”.
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 = 19/fs = 396
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.
2. Zero Detection
The AK4683 has one pin for zero detect flag output. The DZFM1-0 bits select the channel grouping (Table 7). The DZF
pin goes “H” when all of the enabled channels are continuously zeros for 8192 LRCK cycles. DZF pin immediately
goes to “L” if input data of any enabled channel is not zero after going DZF “H”.

3. Validity Detection
The AK4683 has Validity Detection function. DIR decodes the V bit and output “H” via pin. When unlocked, “L” is
output.
