 		 #2531 - RE: 8 external interrupts
If you are trying to trigger interrupts on both edges, then an exclusive or gate with a CR delay on one of the inputs is often the way to go. The actual level can determined by a port read.

Isn't it convenient that you mostly get 4x XORs for the price of one too?!
