Hi ,

             I am using ADSP21161N in my product. In recent days I have observed that IRQ2 routine is getting halted. Though the signal connected IRQ2 pin is active.


interruptcb(SIG_IRQ2,InterSample);   // registering the interrupt


As per our design the InterSample routine have to be executed whenever the processor detects a falling edge in the IRQ2 pin.


Is the interrupt get disabled automatically on the fly….?

Is the DSP program get halted…?


Please advise.


Thanks in advance.
