That also was what I saw....so that standard pin is currently free to have that interrupt capability added. Frankly, I am a bit surprised that it wasn't already built in, since the K3 incorporates so many features to try to create flexibility and eliminate the need for external computer interfaces. However, I think it is very encouraging to see that pin #6 is not currently used for some other unusual application, and is still available for this feature to be added. I hope that there is some way that it can be provided.
