    isr component directly detects rising edge. Is this idea going to be work?

      I would like to simplify my hardware design for raising 2 interrupts events with a single digital input pin to detect pulse edges.  So my idea is to use digital input hardware pin to detect pulse falling edge while a isr component to detect a rising edge by connecting to the digital input pin. This trys to raise 2 seperated interrupt events. Make clear that it is not to raise a single event with detecting rising and falling edge. The topdesign is shown as following diagram. Is this going to work? Has anyone have any this experience?
