Embodiment Construction

[0018] The following detailed description refers to the accompanying drawings, which illustrate by way of illustrations specific details and embodiments in which the invention may be practiced.

[0019] The word "example" is used herein to mean "serving as an example, instance, or illustration." Any implementation or design described herein as "example" is not necessarily to be construed as preferred or advantageous over other implementations or designs.

[0020] The word "over" may be used herein with reference to forming a deposition material "on" a side or surface to mean that the deposition material may be formed "directly" on, eg, in direct contact with, the side or surface. The term "over" may be used herein with reference to forming a deposition material "on" a side or surface to mean that a deposition material may be formed "indirectly" on said side or surface that is between the side or surface and the deposition material. There are one or more additional floors in b...

Abstract

In various embodiments, a method (900) for controlling the operation of a transmitter circuit is provided, the method (900) including: detecting (902) a state of a message field within a data message to be sent by the transmitter circuit indicating a bit rate to be used for transmission by the transmitter circuit and switching (904) the mode of operation of the transmitter circuit from a first data transmission mode to a second data transmission mode depending on the state of the message indication field, wherein in the first data transmission mode a first circuit configured to transmit data may be used and wherein in the second data transmission mode a second circuit configured to transmit data may be used. Further, a corresponding controlling circuit is provided.

Description

technical field [0001] In various embodiments, a transmitter circuit and a method for controlling the operation of the transmitter circuit having a first data transmission mode and a second data transmission mode are provided. Background technique [0002] The CAN (Controller Area Network) bus was developed for a variety of distributed industrial systems, automation applications being perhaps its most notable field of application. CAN is a multi-master architecture, which means that each entity (also known as a node) connected to the bus can send and receive messages, but not both at the same time. This is achieved by providing an identifier for each message, which also defines the priority of the corresponding message. To avoid collisions of messages sent simultaneously by different nodes, an arbitration phase precedes each phase in which "payload" data is sent. During the arbitration phase, the node specifying that the message has the highest priority sends the message, ...
