Thanks, Darrel...great info.

I've never had an experience with the timer registers so I think I'll rewrite the stopwatch code just as a self tutorial.

I was just wondering, doing it the way I have based on build counters and instruction cycles there is a chance that the code could get corrupt and miscount as the pic would need a hard reset?

I suppose if you had a reference like the timer you could "reset" based on that or something.

I did see a strange count one time and that's all I could think of.

It'll be fun to study that material.
