TLDR
In this article, the authors provide a bus system having a plurality of stations coupled together by an arrangement of lines and each having a transceiver and a control unit, a microcontroller, or the like, and specify a method of encoding a digital message on a bus systems in which the digital message comprises at least one part that is encoded in a non-bitrate-dependent manner and by means of which method it becomes possible for the transceiver or a system base chip to independently receive and analyze the data transmitted on the bus line.
Abstract
To provide a bus system having a plurality of stations that are coupled together by an arrangement of lines and each have a transceiver and a control unit, a microcontroller, or the like, and to specify a method of encoding a digital message on a bus system in which method the digital message comprises at least one part that is encoded in a non-bitrate­dependent manner and by means of which method it becomes possible for a transceiver or a system base chip to independently receive and analyze the data transmitted on the bus line, and in particular, in accordance with the method, to individually wake a bus node by means of a given wake-up message even when the part of the bus node that is on standby at the relevant point in time does not have an accurate timer and also does not have any knowledge of the bitrate at which the data is transmitted on the bus, provision is made, under the bus system according to the invention, for at least one transceiver (100) to comprise means for the non-bitrate-dependent analysis of digital signals and, under the method according to the invention, for the value of a bit in that part of the message that is encoded in a non-bitrate­dependent manner to be represented by the lengths of successive dominant and recessive phases.

Definition of wakeup bus messages for partial networking

TL;DR: In this paper, the authors propose a method of encoding a digital bus message information, in particular a wake-up bus message or configuring data, on a bus system, the method comprising: encoding a predetermined part of digital bus messages bits by means of sub-patterns in a stream of line symbols on at least one bus line, wherein subpatterns consist of successive dominant and recessive phases, comprised of recessive and dominant line symbols, respectively, and a recessive phase is comprised of at least two recessive line symbols in order to establish a ratio of successive

Method of arbitrating access to a data bus and apparatus therefor

TL;DR: In this article, a method of handling erroneous messages in a data processing arrangement is proposed. But the method is performed by causing the station which detected the erroneous message to transmit an error report in response to the erroneous messages; and, causing the error report to include a sequence of states or bits which cannot be confused with any sequence of dominant states or bit during error-free data transmission.
