A turbocharger unit for a multicylinder internal combustion engine has at least two exhaust lines for the evacuation of exhaust gases from the combustion chamber of the engine and at least one inlet line for the supply of air to the combustion chamber. A stator includes a swirl passage configured to guide the secondary flow so as to be discharged from a pre-swirl nozzle. The reference may have a low update rate. When a new state change is received, the address of the corresponding device is compared against each of the addresses currently stored in the buffered RSCN frame.
