The following table shows the main steps of an interrupt and the order in which they are per-
formed according to the mode:
Notes:
Action
Calculate active interrupt
(higher than current or spurious)
Determine and return the vector of the
active interrupt
Memorize interrupt
Push on internal stack the current priority
level
Acknowledge the interrupt
No effect

in Normal Mode without modification. However in Normal Mode the AIC_IVR write has no
effect and can be removed to optimize the code.
