Question

Wakeup over CAN on SPC58EC

Hi there,

I am working with a company developing an automotive control module that connects to several systems that must be able to wake up the module from STOP mode.

One of the modules signals the wakeup request over the CAN bus, and I was wondering if it was possible to integrate this functionality into the firmware of the SPC58EC microcontroller.

I had a read through both the WKPU and MCAN sections of the datasheet, and could not find any conclusive information about how I might go about this or whether this functionality is supported in this microcontroller.

Any suggestions for implementation of this functionality, or alternative microcontrollers that may provide this functionality will be greatly appreciated.

Kind regards,

-Graison

    Hello Graison ,

    I think that Wakeup on CAN is possible. (cf chapter WKPU)

    Interruption mapping is necessary.

    I am trying to find an application note to explain how to configure the CAN in Wakeup mode.

    Best Regards
