Hi,
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?
Solved! Go to Solution.
Hi Liangliang,
Please download the MKL28ZRM, then read the chapter "3.11.1.1 Port control and interrupt summary".
Best Regards,
Robin

So there is no digital glitch filter on MKL28Z7, what a shame. Thanks for your reply anyway.
How about the passive input filter on PTA4 and PTB19, I cannot find specific document anywhere. I guess it is comprised by the pin internal pull up register (20kΩ~50kΩ), and 25pF pin load for normal/low drive pins, right?
Hi Liangliang,
You can find analog/passive filter specifications in DataSheet(MKL28Z512VXX7):
