Software Mode Definitions
SCL/CCLK
Serial Control Port Clock (Input) - Serial clock for the serial Control Port. Requires an external pull-up
15 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
