I just tried watching digital 2 on my picscope and for some reason the 22k resistor seemed to allow the voltage to spike (or my cheesey picscope didn't like it for some other reason). Without it, the signal at the cpu pin was pretty clean.

Coyote (or anyone) If you get a chance with your fancy o-scope to measure the effects of the additional resistor at the CPU, I would greatly appreciate it. But at the moment I don't think we have a "peak and hold" solution.
