Handlig of VICVectAddr in FIQ

2005-09-21 by Marko Panger

Hi all,

I have a doubt regarding the handling of the VICVectAddr register in a
FIQ rutine.

My VIC is setup in such a way that I have just one source selected as
FIQ, thus is not vectored as other IRQs are.

Do I still have to acknowledge and update priorities near the end of
the FIQ handler by writting the VICVectAddr = 0; ?

I dont get the users manual very well at this point as it says that
the VIC should be updated for vectred interrupts, but my FIQ is not
vectored.

Any advice ?

Regards,
marko
