[Adeos-main] Re: My first tests with adeos!!!

[mohan kumar]

hi,
I assume that resetting the control word (with the
IPIPE_PASS_MASK bit set) will dispatch the interrupt
to the next domain. So i reset the control word once
every 100 interrupts and reset it in the next
interrupt.

Well, my code is not elobrate :)

cheers,
Mohan S
