Re: spurious interrupts on LPC

2006-03-15 by Jayasooriah

Paul,

If you read my original post carefully, you will realise that I was talking 
about spurious interrupts, not nested interrupts or interrupt lockouts.

The word "spurious" applied to interrupts means "lacking authenticity or 
validity as to its origin".

The existence of an interrupt for which the system cannot identify its 
source is deemed as a system failure, and hence kernel "panics" in 
certified OSes.

But we are talking about VIC, more specifically in the context of ARM7TDMI.

Where spurious interrupt indicate system failure, any workaround that 
relies on ignoring these interrupts is not a solution.
