I am trying to use TMR0 to synchronize my code length, but when I simulate
with the stopwatch running the STOPWATCH increments 2 cycles(exactly
following single step mode) for every TMR0 cycle on average.  I do not have
the prescaler turned on.

I initialize TMR0 with the following code:

movlw   b'00000000'
option

Any suggestions?
Thanks, Greg.
