  • System and methods for enabling a controller area network (CAN) device to operate in different power modes based upon the payload of a wake-up message
    Patent number: 9112721
    Abstract: Systems and methods for handling wake-up messages in a Controller Area Network (CAN) are described. In some embodiments, a method may include operating a CAN controller in a selected one of a plurality of operating modes in response to the detection of an event or activity on a CAN bus. The method may also include handling, by the CAN controller, a CAN message using a message handling protocol associated with the selected one of the plurality of operating modes, for example, while a host processor operates in a low power mode. In various implementations, each of the plurality of operating modes may correspond to a different amount of power consumption by the CAN controller. The method may further include transmitting a selected one of a plurality of response messages by the CAN controller over the CAN bus, in some cases, without waking up the processor from the low power mode.
