Ok....that's a new one. A NOP?

Everything I think is fine...as always a stupid mistake on my part by not taking PORTB.0 low with a pulldown and letting it float....(a great way to get "unpredictable" behavior).

It was probably sensing a false high and interfering with the sleep routine.

I had put a pause following sleep as I had read in the archives (Melanie?) suggested it's use, to let the PIC wake up and get some coffee.

Maybe what your saying is the NOP would do the same thing?

Sort of a safety buffer before it gets back to work?
