i am trying to use the analog comparators in the SAMD21G. The datasheet stated there are only two comparators but table 7-1 port function multiplexing there are two outputs for each of those comparators so total four outputs.
my questions is why are there two AC/CMP and two AC/CMP? If i am only use comparator 1 which output is the correct one to use??? The pin multiplexed to pin 22 or pin 28?
