Abstract:
1. A device for providing a line termination of a two-wire line, wherein the two-wire line is a part of a CAN bus system, comprising: a first terminating resistor and a second terminating resistor provided between the two wires of the two-wire line, wherein the first and the second terminating resistors are connected in series; at least one switching arrangement provided between the first and second terminating resistors, wherein the at least one switching arrangement is configured to separate the first and second terminating resistors from the two-wire line, and wherein the device assumes at least one of a receive function and a transmit function in the CAN bus system; a control logic configured to control the at least one switching arrangement based on a control signal from a microcontroller sent over a first communication channel; and a driver module configured to provide at least one of a unidirectional and bidirectional communication with the microcontroller over a second communication channel.
