Hi, when a source of interrupt is connected in fast interrupt mode, the priority is the same as normal interrupt?
It's higher: FIQ can interrupt an on-going IRQ but the reverse is not true.
Thanks, i'm not able to read this information from the documentation,
You are saying that fast interrupts can interrupt normal IRQ, so they are nested?
Yes, that info is a bit difficult to find. You can find it in the "Exception Handling" section of the "Cortex-A Series Programmer's Guide".
Sorry i wasn't specifying my architecture, i use Xintc core on a Microblaze system, i'm not using Arm
