Serial Control Data (Input/Output) - SDA is a data I/O in I²C® Mode. CDOUT is the output data line for

the control port interface in SPITM Mode.

2 Serial Control Port Clock (Input) - Serial clock for the serial control port.

3

Address Bit 0 (I²C) / Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in I²C Mode;

CS is the chip-select signal for SPI format.

4

Address Bit 1 (I²C) / Serial Control Data Input (SPI) (Input) - AD1 is a chip address pin in I²C Mode;

CDIN is the input data line for the control port interface in SPI Mode.

5

Control Port Power (Input) - Determines the required signal level for the control port interface. Refer

to the Recommended Operating Conditions for appropriate voltages.

6 Reset (Input) - The device enters a low-power mode when this pin is driven low.

7 Stereo Analog Input 3 (Input) - The full-scale level is specified in the ADC Analog Characteristics

8 specification table.

9 Stereo Analog Input 2 (Input) - The full-scale level is specified in the ADC Analog Characteristics

10 specification table.
