Power-Down Mode Pin
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
"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,
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
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,
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".
DAC4 Lch Analog Output Pin
No Connect
No internal bonding.
DAC4 Rch Analog Output Pin
No Connect
No internal bonding.
DAC3 Lch Analog Output Pin
No Connect
No internal bonding.
DAC3 Rch Analog Output Pin
No Connect
No internal bonding.
DAC2 Lch Analog Output Pin
No Connect
