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 Dia-
gram.
SDA/CDIN
16
Serial Control Port Data (Input/Output) - SDA is a data I/O line in I²C mode and is open drain,
requiring an external pull-up resistor to the logic interface voltage, as shown in the Typical Con-
nection Diagram; CDIN is the input data line for the control port interface in SPI
™
mode.
AD0/CS
17
Address Bit 0 (I²C) / Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in I²C
mode; CS is the chip select signal for SPI mode.
