Serial Audio Interface Power (Input) - Determines the required signal level for the serial audio inter-

face. Refer to the Recommended Operating Conditions for appropriate voltages.

Software Mode Definitions

SCL/CCLK

Serial Control Port Clock (Input) - Serial clock for the serial control port. Requires an external pull-

15 up resistor to the logic interface voltage in I²C® Mode as shown in the Typical Connection Diagram.

SDA/CDIN

Serial Control Data (Input/Output) - SDA is a data I/O line in I²C Mode and requires an external pull-

16 up resistor to the logic interface voltage, as shown in the Typical Connection Diagram. CDIN is the

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

AD0/CS
