Zero Input Detect Pin
When the input data of DAC follow total 8192 LRCK cycles with “0” input data, this
pin goes to “H”. And when RSTN1 bit is “0”, PWDA bit is “0”, this pin goes to “H”.
Analog Input Overflow Detect Pin
This pin goes to “H” if the analog input of Lch or Rch overflows.
Control Data Output Pin in Serial Mode and I2C pin = “L”.

When DIT bit = “0”, RX0~3 Through.
When DIT bit = “1”, Internal DIT Output.
Master Clock Input Pin
Power-Down Mode & Reset Pin
When “L”, the AK4683 is powered-down, all registers are reset. And then all digital
output pins go “L”. The AK4683 must be reset once upon power-up.
Control Data Input Pin in Serial Mode and I2C pin = “L”.
Control Data Pin in Serial Mode and I2C pin = “H”.
Control Data Clock Pin in Serial Mode and I2C pin = “L”
Control Data Clock Pin in Serial Mode and I2C pin = “H”
Chip Select Pin in Serial Mode and I2C pin = “L”.
This pin should be connected to DVSS in Serial Mode and I2C pin = “H”.
