According to the EZR32WG330 datasheet, GPIO0 is wired to PA15 and GPIO1 is wired to PE14. So why is the PRS necessary? Couldn't I just set up PA15 and PE14 as push-pull outputs (or inputs)?
@andrasbiro What exactly do you mean by "only want to monitor"? What you are saying seems to be contradicting what the datasheet says.
@andrasbiro Thanks, this clears it up. So basic GPIO should work fine and the purpose of the PRS here is to do things other than basic GPIO, right?
