Function
Power-Down Mode Pin
I
When “L”, the AK4589 is powered-down, all digital output pins go “L”, all registers
are reset. When CAD1/0 pins are changed, the AK4589 should be reset by PDN pin.
I
Master Mode Select Pin
“H”: Master mode, “L”: Slave mode
Zero Input Detect 2 Pin
(Table 13)
O
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 pin is “H”.
O
Analog Input Overflow Detect Pin
This pin goes to “H” if the analog input of Lch or Rch overflows.
Zero Input Detect 1 Pin
(Table 13)
O
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 pin is “H”.
