The invention relates to a control unit (5) for interrupting the processing of a data packet, incoming into a communication unit. Said control unit (5) comprises a comparator device for comparing the target address of said data packet with at least one preset address. Said control unit (5) interrupts the data packet processing, by at least partially disconnecting the receiver unit (1), as soon as said control unit determines that the target address does not correspond to the preset address, whereas if said control unit determines that both addresses correspond to each other, i. e. that the data packet is intended for the receiving communication unit, said control unit does not interrupt the processing and the entire data packet is properly received. The comparison between the addresses occurs before the entire data packet is processed.
