- 7 -
No. Pin Name I/O Function
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 the PDN pin.
32 MASTER I
Master Mode Select Pin
“H”: Master mode, “L”: Slave mode
DZF2 O
Zero Input Detect 2 Pin (Table 13)
When the input d
ata 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”.
33
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 d
ata 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”.
