2 CODEC Serial Clock (Input/Output) - Serial clock for the CODEC serial audio interface.
3 CODEC Left Right Clock (Input/ Output) - Determines which channel, Left or Right, is currently active on
the CODEC serial audio data line.
4 Digital Power (Input) - Positive power supply for the digital section.
51
5 Digital Ground (Input) - Ground reference. Should be connected to digital ground.

6 Control Port Power (Input) - Determines the required signal level for the control port.
7 Serial Control Port Clock (Input) - Serial clock for the serial control port. Requires an external pull-up
resistor to the logic interface voltage in I2C mode as shown in the Typical Connection Diagram.
8 Serial Control Data (Input/Output) - SDA is a data I/O line in IC mode and requires an external pull-up
resistor to the logic interface voltage, as shown in the Typical connection Diagram. CDOUT is the output
