Data Format and Bus Receiver
The circuit receives the information for tuning and control
via the I2C bus. The incoming information, consisting of a
chip address byte followed by two or four data bytes, is
treated in the I2C bus receiver. The definition of the
permissible bus protocol is shown below:
