Software Mode Definitions

SCL/CCLK

15

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.

SDA/CDIN

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

16 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
