I2C Trigger (Option)

I2C is a 2-wire serial bus used to connect the microcontroller and its peripheral
device. It is a bus standard widely used in the microelectronic communication control
field.
The I2C serial bus consists of SCL and SDA. Its transmission rate is determined by SCL,
and its transmission data is determined by SDA, as shown in the figure below. The
instrument series triggers on the start condition, restart, stop, missing
acknowledgment, specific device address, or data value. Besides, it can also trigger on
the specific device address and data values at the same time.
