Cci is a subset of the i2c protocol, including the minimum combination of obligatory features for i2c slave devices specified in the i2c specification. You can see that the i2c interface is labelled as master (this means that the camera owns the bus) and, reading a bit more, you will find that the only usage for this is to allow.
