ACTION NORMAL MODE ICE/DEBUG MODE
Calculate active interrupt Read AIC_IPER Read AIC_IPER
Determine and return the vector of the active interrupt Read AIC_IPER Read AIC_IPER
Push on internal stack the current priority level Read AIC_IPER Write AIC_IPER
Acknowledge the interrupt (Note 1) Read AIC_IPER Write AIC_IPER
No effect (Note 2) Read AIC_IPER
Notes:
y nIRQ de-assertion and automatic interrupt clearing if the source is programmed as
level sensitive.
y Note that software which has been written and debugged using this mode will run
correctly in normal mode without modification. However, in normal mode writing to
AIC_IPER has no effect and can be removed to optimize the code
