In low voltage swing mode, input data = logic HIGH = V
In low voltage swing mode, input data = logic LOW = V
This pin is not to be left floating. When not use in LVTTL mode, tie to V
HIGH to enable two-wire serial communication interface; LOW to disable the
interface.
Always HIGH for one 12-bit port and two 12-bit ports operation. When
I2CSEL = HIGH, this is the clock line for the two-wire serial communication
interface.
Differential select pin for CLKIN (HIGH = single-ended, LOW = differentail)
or when I2CSEL = HIGH, this is the Bidirectional Data line for the two-wire
serial communication interface.
when I2CSEL = HIGH, this is one of the Slave Device Address Lower Bits.
when I2CSEL = HIGH, this is one of the Slave Device Address Lower Bits.
when I2CSEL = HIGH, this is one of the Slave Device Address Lower Bits.
Interrupt signal. This is an open drain output, pull-up resistor is required.
