TC input capture has a special feature, it can store “event polarity” with counter value. This can set by PER register B15 bit (set to 0).
But I do not found reference what is this event polarity.
For example if input pin changed form 0 to 1, then TC input capture event generated. But in this case CC register hold polarity 0 (old state) or polarity 1 (new state) together with counter value?
Other words the CC event carry the new polarity or the old polarity together with counter value?
Thanks for any advise.
