The device supports the I²C protocol (see Figure 4).
The I²C bus is controlled by the bus master and the device is always a slave in all
communications.
The device (bus master or a slave) that sends data on to the bus is defined as a transmitter;
the device (bus master or a slave) is defined as a receiver when reading the data.
