Pins for timing

Hey everyone!

I am trying to pinpoint when certain operations in aes happen and figured the best way would to be outputting a signal to somewhere else on the board when they happen and measure it with an oscilloscope. Are there any pins other than the trigger pin that may be used for this? I suppose I could just change the trigger pin to work for my own nefarious purposes since I’m not using a ribbon-connected oscilloscope, but I was wondering what other options I have.


Nevermind, I ended up just hijacking the trigger pin and I suppose since I am not using the XMEGA board I could just steal some pins from the 20-pin connector.
