Interrupt handling

[Altera_Forum]

Hi, 

I connected a counter pin to the PIO in order to generate IRQ every 256 cycles. Appropriate IRQ handler is called after the interrupt triggers. However, after handling the interrupt, the alt_irq_handler stays in the loop because ipending is still set. So, how shall I clear the interrupt request ?   Best regards, Joel

In the handler routine reset the edge register by writing 0 to it or ones ( ones didnt work for me but the manual states it) in dependence of PIO configuration.
