TMS570LS3137: svc soft interrupt issue

Part Number: TMS570LS3137

Hi Team,

At present, I want to trigger another interrupt in the RTI timer interrupt handler to perform the corresponding task, and only soft interrupts are currently in mind. There are two questions:

1) Is the soft interrupt priority lower than the priority of the IRQ, that is, it cannot be nested, and the handler of the soft interrupt needs to be executed after the RTI interrupt processing is executed?

2) How to trigger a soft interrupt? No relevant cases were found

 

Regards,

Susan
