Abstract: Embodiments of a method, a device and a computer-readable storage medium are disclosed. In an embodiment, a method for operating a Controller Area Network (CAN) device involves detecting a transition of a CAN transceiver of the CAN device from a dominant state to a recessive state and in response to detecting a transition of the CAN transceiver from the dominant state to the recessive state, controlling an output impedance of the CAN transceiver to be within a predefined range of an impedance value at the dominant state while a differential driver voltage on a CAN bus connected to the CAN transceiver decreases to a predefined voltage.

Abstract: A Controller Area Network, CAN, transceiver configured to be connected to a CAN bus comprising; a transmitter arrangement configured to transmit signalling on the CAN bus based on transmit data, configured to operate in a first or second transmission mode, the first transmission mode configured to transmit said signalling with a first property and the second transmission mode configured to transmit said signalling with a second, different, property; a receiver arrangement configured to receive signalling from the CAN bus; a receive output configured to provide received data to the CAN controller; and wherein the transmitter arrangement is configured to operate in one of the first or second transmission modes based on a determination that the transmit data is encoded with a first line code and otherwise operate in the other transmission modes, and wherein the transceiver includes a decoder configured to decode the first line code of the transmit data.

Abstract: The disclosure relates to a controller and a transceiver and associated software and methods. A controller for communicating with a transceiver in a network node having a first mode of operation and a second mode of operation, the controller comprising: a first-data-terminal for communicating with the transceiver; and a second-data-terminal for communicating with the transceiver, in which the controller is configured to: in the second mode, determine receive-data based on a first-data-signal at the first-data-terminal and a second-data-signal at the second-data-terminal; determine that a change of mode from the second mode to the first mode is required; and in response to determining that a change of mode from the second mode to the first mode is required, provide a controller-mode-signal that instructs the transceiver to operate in the first mode rather than the second mode, wherein the controller-mode-signal is provided by simultaneously driving a first current on the first-data-terminal and a second current on the second-data-terminal.
