Does AM1808 support level sensing interrupt on the GPIO pins?

I have an active low interrupt source, but the AM1808 seems not supporting level sensing interrupt on the GPIO pin, how can I make it as level sensing?

    The GPIO on AM1808 does not have level sensing interrupt.  There is only edge sensing.  You can trigger on either rising edge, falling edge, or both. 

    For instance, if you want to determine when your signal goes active (low), you can configure the GPIO to trigger an interrupt on the falling edge (going from high to low).
