Registering more Interrupts

Hello,

after modifying the examples of the tutorial - button interrupts - to a one 1 bit PIO via VHDL access, I put a second 1 bit PIO as an input interrupt. How do I create and then handle those two interrupts parallel and perform the exception control?

I didn't find anything about parallel interrupts in the the tutorials or manuals. Either did I find more example code than provided with the button-pio.

Thanks in advance.

    What do you mean by parallel interrupts?

    --> you mean two 1-bit PIO components --> then you have two separate IRQs

    --> you mean a single 2-bit PIO component --> then you have a single interrupt that should be raised when the interrupt condition appear on one of the pins...
