# Pin Description
1
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 SPI 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.
