OMAP-L138: AINTC Interrupt Nesting

Part Number:OMAP-L138


Hi all,

I'm investigating the interrupt nesting of AINTC in OMAP-L138.
Could anyone tell me about the difference in behavior between 'Nesting for all host interrupts' and 'Nesting for individual host interrupts'?

Image may be NSFW.
Clik here to view.


I think that in Method 2, if an FIQ interrupt occurs during IRQ processing, the FIQ interrupt is kept waiting. Is my thinking correct?
Please tell me the use cases of Method 1 and Method 2.

Best regards,
H.U
