Hi,

I want to use the XMC1400 boot kit to analyze CAN Messages from 5 different nodes.
Therefore I would need to create 5 Interrupts for 5 CAN Rx LMOs. The XMC1400 only supports 4 HW Signal Connections to one Interrupt each (XMC1400 Reference Manual Chapter 18.6.4.4, I also get the hardware resource error).
What is the best way to bypass this limitation?

Hi,

Have a look at Figure 18-16 Message Interrupt Request Routing. You will need to check CAN_MOSTATn which message was responsible for triggering the interrupt.
