| 1. A method for transmitting data via a data transmission unit between data processing units of a data processing system,
transmitting the data in parallel in at least a first protocol and a second protocol;
based on the first protocol, transmitting first data of the data in a first frequency range with a first signal sequence and
a first signal level; and
based on the second protocol, transmitting second data of the data in a second frequency range with a second signal sequence
and a second signal level;
wherein a first switching level of the first protocol differs from a second switching level of the second protocol.
