Standby Mode is performed with TC3xx, and Wakeup is considered using CAN.
Do I need to use SCR to wakeup?

When CAN communication is detected by SCR, how to wakeup from SCR to TC3xx?
I don't know what to do.


1, CAN interrupt detection with SCR
2, Notify TX3xx with SCRINTEXCHG
3, Detect CAN notification by PMSWCR2.SCRINT on TC3xx side
4, After operation 3, reset the software

Are the above steps correct?
If correct, will the TC3xx be able to detect PMSWCR2.SCRINT because it is in Standby mode?

Please help me.

Hi,

You can check the following sections from "AURIXTC3XX_um_part1_v2.0.pdf" to identify your system configuration and check the wake-up path based on that.
11.2.3.4.1 Standby Mode with only VEVRSB domain supplied and VEXT domain switched off
11.2.3.4.2 Standby Mode with both VEXT and VEVRSB supplied via common supply rail.

You can mention the configuration at your end for us to check more about your question.


You can also refer to the below section.
11.2.3.4.11 Exiting Standby Mode - Wake-up event

Best Regards.

I read the document and could not understand it, so I am asking a question as the operation of the software.

Is my question correct?

If I'm wrong, please show me the correct steps.

2. From section "11.2.3.4.11 Exiting Standby Mode - Wake-up event", is there any specific question?
