I/O Function
Power-Down Mode Pin
I When "L", the AK4588 is powered-down, all output pin goes "L", all registers arereset.
When CAD1/0 pins are changed, the AK4588 should be reset by PDN pin.
Master Mode Select Pin
I
"H": Master mode, "L": Slave mode
Zero Input Detect 2 Pin
When the input data of the group 1 follow total 8192 LRCK cycles with "0" input data,
O
this pin goes to "H". And when RSTN bit is "0", PWDAN bit is "0", this pin
goes to "H". It always is in "L" when P/S is "H".
Analog Input Overflow Detect Pin
O
This pin goes to"H" if the analog input of Lch or Rch overflows.
Zero Input Detect 1 Pin
When the input data of the group 1 follow total 8192 LRCK cycles with "0" input data,
O
this pin goes to "H". And when RSTN bit is "0", PWDAN bit is "0", this pin goes to "H".
Output is selected by setting DZFE pin when P/S is "H".
