CONTROLLER AREA NETWORK (CAN) DEVICE AND METHOD FOR EMULATING CLASSIC CAN ERROR MANAGEMENT
First Claim
1. A Controller Area Network (CAN) device comprising:
- a transmit data (TXD) input interface;
a TXD output interface;
a receive data (RXD) input interface;
an RXD output interface;
a traffic control system connected between the TXD input and output interfaces and between the RXD input and output interfaces, and configured to;
detect the presence of classic CAN traffic on the RXD input interface; and
if the presence of classic CAN traffic is detected on the RXD input interface, emulate an error management protocol of a classic CAN controller in response to signals received on the TXD input interface.

Abstract
Embodiments of a device and method are disclosed. In an embodiment, a CAN device is disclosed. The CAN device includes a transmit data (TXD) input interface, a TXD output interface, a receive data (RXD) input interface, an RXD output interface and a traffic control system connected between the TXD input and output interfaces and between the RXD input and output interfaces. The traffic control system is configured to detect the presence of classic CAN traffic on the RXD input interface and if the presence of classic CAN traffic is detected on the RXD input interface, emulate an error management protocol of a classic CAN controller in response to signals received on the TXD input interface.
