ADO/CS

Address Bit 0 (Two-Wire) / Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin

Two-Wire mode; CS is used to enable the control port interface.

AD1/CDOUT

AD1/CDOUT - Address Bit 1 (Two Wire) / Serial Control data out (SPI) (Input/Output) - In

Two- Wire mode, AD1 is a chip address pin. In SPI mode, CDOUT is the output data from the

control port interface.

SDA/CDIN

Serial Control Data (Input/Output) - SDA is a data I/O line in Two-Wire mode and requires an

external pull-up resistor to the logic interface voltage. CDIN is the input data line for the control

port interface in SPI mode.

Digital Interface Format (Input) - The required relationship between the Left/Right clock, serial

clock and serial data is defined by the Digital Interface Format and the options are detailed

below

AD1/CDOUT

Non-applicable (input) - non-functional in this mode should be connected to ground.

DEM

De-emphasis Control (Input) - Selects the standard 15

µs/50 µs digital de-emphasis filter

response at 44.1 kHz sample rates. NOTE: De-emphasis is not available in Double or Quad

Speed Modes. When DEM is grounded, de-emphasis is disabled.
