Hi, Russ

[quote]
What happens to the minimum HPWM frequency if a lower oscillator frequency is programmed?
[quote]

PBP calculations are based upon the Define OSC you've entered. ( default is 4 )
HPWM module drive is based upon the Main OSC Period.

so, the real HPWM frequency at output will raise ... in the inverse ratio ...



NOW, if your XTAL has a lower frequency than declared ...

HPWM frequency will be lower ... in the same ratio.


I saw you've got the patent for the " Wine Oscillator " ... Great !!! Congratulations ( ROFL )
