I guess that's a hard one to answer!
I see that PBP lets me go up to 65,535 however having a value of greater than 62000 the frequency goes down. Which I can understand with a 4MHz OSC.

I had the circuit running since yesterday with:
Code:
HPWM 1,127,60000
Which gives 62.7KHz and it is still going so I will stick with the possibility that there is a mistake in the PBP manual unless someone comes up with a better explanation.
I am using 2.60 and manual is dated 6/09.
