I am trying to use the PDLY block to detect a falling edge of a signal following AN 1046 but I cannot get it to work. I have a switch which on pressing goes low. This is fed as input to the PDLY block. It's output is connected to an output pin. I have attached my configuration. Can you please tell me what is missing here. I am expecting a high pulse at the output pin, going by the app note. I also tried the FILTER block, but in vain.
