Thanks for your response, I did try, but something very odd happens, I changed it to an infinite loop to produce a frequency that I can measure:

Loop:
Toggle PulsePin
@NOP
@NOP
@NOP
@NOP
@NOP
@NOP
@NOP
@NOP
@NOP
@NOP
GOTO Loop

But for some reason, no matter how many @NOP I add, the frequency does not change and stays at 62.5 KHz

Any Ideas?
