I read from the MKL28Z7 user manual that there is a digital filter function for the digital input pins, but I can not find the list of the pins that has this function. I tried on all the ports, seems the DFER, DFCR, DFWR registers of all the ports are read only. So where I can find more information about this digital filter function?
