an interface with the at least one microcontroller, or for a second mode in which the at least one interface controller is
integrated into the at least one microcontroller;

the transceiver unit includes a plurality of transceivers and a bootstrap circuit; and
the bootstrap circuit generates synchronization pulses for the transceivers in a staggered fashion such that the transceivers
receive respective synchronization pulses at different times.
