I/O
— PLL Power supply, 4.5V~5.5V.
I Receiver Channel 0 (Internal biased pin. Internally biased at PVDD/2).
I Control Mode Select.
"L": 4-wire Serial, "H": I2C Bus
I Receiver Channel 1.
I Receiver Channel 2.
I Receiver Channel 3.
O Interrupt
O Zero Input Detect.
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"
O Control Data Output in Serial Mode and I2C pin = "L".

— Output Buffer Power Supply, 2.7V~5.5V
— Digital Ground
— Digital Power Supply, 4.5V~5.5V
I X'tal Input
O X'tal Output
O Transmit Channel Output
When DIT bit = "0", RX0~3 Through.
When DIT bit = "1", Internal DIT Output.
I Master Clock Input
I Power-Down Mode & Reset
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.
I/O Control Data in Serial Mode and I2C pin = "H".
I Control Data Clock in Serial Mode and I2C pin = "H".
I Chip Select in Serial Mode and I2C pin = "L".
