I am trying to determine and control interrupt priorities on the ZC7010 ARM.
I can set IRQ and private timer priorities e.g.:
XScuGic_SetPriorityTriggerType(&IntcInstance, XPS_FPGA0_INT_ID, 0x08, 3);
How do I set or determine the USB interrupt priority?
Also, are interrupts nested?
Is a lower priority ISR interrupted by a higher priority ISR?
Is there another doc besides UG585?
I have read in posts that for:
the lower the number, the higher the priority.
Where is this documented?
Can interrupts be nested?
Can a higher priority ISR interrupt a lower priority ISR?
