#30888 - RE: Faulty ISR???

-------------------------------
I had posted the part of the code where i thought i had made the mistake. i assumed that the init was ok. but according to one of peter's post, from a very very long time ago, we need to inculde two reti's in case of a software interrupt. (something i wasn't aware of)
----------------------------
P.D. had posted:

Conclusion:
Execute a RETI to reset the interrupt logic.
On using 2 interrupt priorities do it twice and
on 4 interrupt priorities (e.g. at the C505) 4 times
------------------------------
sushil,as you see you need 2 RETI only when cascaded interrupts are possible.this happens only when multiple priorities are set.
