delay pulses control through AVRAtmega16

[oxama]

hello every body ..
please help me ..
i am stuck in Avrprogramming
i made a program , using atmega16 for controlling the firing angle/delay angle of gto or igbt.
i attach my code and schematics below
code runs good when i not attach the Zero crossing detector
but as soon i attach ZCD it fails to give output properly.
i guess i code stucks in ISR,
can anybody please help me?? if my querry is,nt clear , i guess from attached file it will be effectively clear please help me ..!!

I notice that you have connected your 'zero-cross-detector' to both INT0 and INT1. Why both ?

Secondly in your code, you have commented out the MCUSR and GICR initialisation pieces. Where are you doing this instead ?
In the absence of this initialisation, i'm not sure how the interrupts will function.

Lastly - you stated that code works good w/o detector. If so, how did you test the code without this input ?

thx for ur responce..
well ZCD with INT0 and INT1 bcz i need to fire two igbts separately... if i m wrong kindly correct me..
moreover that GICR and MCUSR is commented bcz if i run the proteus ciruit by including that part of code circuit doesnt runs properlyy..
As i need to varry the delay of ZCD pulses and that commented part of code is actuall code of the ZCD..
for ur last question i guess u will get clear answer if u run that circuit with that code..
i hope u will find some remedy of this querry then..
