I enabled PIO1_3 and PIO1_4 as inputs for two push buttons. Since the beginning I chose to enable the digital glitch filters, but the GPIO1's state never changed when pressing any of the two buttons.
After some experiments I noticed that when the digital filters were enabled then the pins' state doesn't change as in (1); however, when the filter is disabled then the pin's state effectively changes whenever I press the button on that pin (as in (2)).
Is there anything else to enable in the core before using the glitch filters?
