摘要:
A method of encoding a digital bus message information, in particular a wake-up bus message information or configuring data, on a bus system, the method comprising: encoding a predetermined part of digital bus message information bits by means of sub-patterns in a stream of line symbols on at least one bus line, wherein sub-patterns consist of successive dominant and recessive phases, comprised of recessive and dominant line symbols, wherein a recessive phase is comprised of at least two recessive line symbols in order to establish a ratio of successive dominant and recessive phases that corresponds to a value of the predetermined part. A respective digital bus message, particularly for use on a bus system, is to be encoded in accordance with the method.Further, a bus node for a system bus having a plurality of stations that are coupled together by means of an arrangement of bus lines, comprises decoding circuitry configured for an analysis of sub-patterns in a stream of data on at least one bus line, and analysing circuitry configured to detect encoded digital bus message information, in particular a wake-up bus message information or configuring data, transmitted in a stream of line symbols on the bus system, wherein the digital bus message information is encoded in accordance with the method.
