Interrupt priority IIR

Hi,

1. The one in the NIOS II Software Developer's handbook tells me to use two functions:

alt_irq_interruptible() and alt_irq_non_interruptible()

to "bracket code in a processor-intensive ISR.

--- Quote End ---

I would use that in order to make your ISR interruptible.

2. In the NIOS II Processor Reference Handbook it tells to enable nested interrupts by setting the status.PIE Register to 1 near the beginnung of an ISR. How? By calling alt_irq_enable_all()? If yes, which argument should I apply?

--- Quote End ---

I think, this is done by alt_irq_interruptible().
