Control Port Mode

CLKMODE 34

CLKMODE (Input) - This pin is ignored in Control Port Mode and the same functionality is

obtained from the corresponding bit in the Global Control Register. Note: Should be connected

to GND when using the part in Control Port Mode.

AD1/CDIN 37

I²C Format, AD1 (Input) - Forms the device address input AD[1].

SPI Format, CDIN (Input) - Becomes the input data pin.

AD0/CS

I²C Format, AD0 (Input) - Forms the device address input AD[0].

SPI Format, CS

(Input) - Acts as the active low chip select input.

SCL/CCLK 39

I²C Format, SCL (Input) – Serial clock for the serial control port. An external pull-up resistor is

required for I²C control port operation.

SPI Format, CCLK (Input) – Serial clock for the serial control port.

SDA/CDOUT 40

I²C Format SDA (Input/Output) - Acts as an input/output data pin. An external pull-up resistor is

required for I²C control port operation.

SPI Format CDOUT (Output) - Acts as an output only data pin.

MDIV 42

MCLK Divider (Input) - This pin is ignored in Control Port Mode and the same functionality is

obtained from the corresponding bit in the Global Control Register.

Note: Should be connected to GND when using the part in Control Port Mode.
