Post by kataklinger »

What happen to IPIs when Interrupt Flag is 0?
Are they also masked?

Hi,

The IPIs behave like an IRQ when the interrupts are disabled.

The only interrupts that the IF flag doesn't control are exceptions, NMIs, SMIs, STARUP IPIs, INIT IPIs (both assert and d-assert) and ExtINT.


Cheers,
