31 PDN I
Power-Down Mode Pin
When “L”, the AK4588 is powered-down, all output pin goes “L”, all registers are reset.
When CAD1-0 pins are changed, the AK4588 should be reset by PDN pin.
32 MASTER I
Master Mode Select Pin
“H”: Master mode, “L”: Slave mode
33
DZF2 O
Zero Input Detect 2 Pin (Table 13)
When the input data of the group 1 follow total 8192 LRCK cycles with “0” input data, this pin goes to
“H”. When RSTN1 bit is “0” or PWDAN bit is “0”, this pin goes to “H”.
OVF O
Analog Input Overflow Detect Pin
This pin goes to “H” if the analog input of Lch or Rch overflows. This pin becomes OVF pin if OVFE
bit is set to 1.
34 DZF1 O
Zero Input Detect 1 Pin (Table 13)
When the input data of the group 1 follow total 8192 LRCK cycles with “0” input data, this pin goes to “H”.
When RSTN1 bit is “0” or PWDAN bit is “0”, this pin goes to “H”.
