Dear All


I am using DEVKIT-MPC5744P Board (REV-E).

I am using a GPO to toggle a pin and using the same ping to provide input to another GPI

I am trying to use Rising Edge Detection and Falling Edge Detection using different GPI ISR blocks. (shown below) 


To test i use an LED. for falling edge it shall be off and for rising edge it shall be on. But the LED stays on. Somehow both ISR for same pin is not working in this toolbox. Please provide your input.

Model is attached.
