A question on defining the external oscillator

[ozarkshermit]

Thanks Melanie

Yes, what you suggested is what I did initially to find that adding DEFINE OSC 20 changed the timing on a blinking LED (using some PAUSE statements) back to what it was at 4 MHZ.

I guess I should have looked at page 172 of the manual a little closer.

From that I gather then, only the "timing - related" commands will operate at basically a 4MHX clock rate, - and everything will be faster by a factor of 5 ..

I need the extra speed to get through a lot of IF-THEN statements faster.

Thanks

Ken

Yes you are correct. Only Timing Critical commands will be brought back into line (eg PAUSE, PAUSEUS etc) in order to operate correctly (not nescessarilly to operate at 4Mhz but to operate CORRECTLY at your processor speed). All others will be quicker x500%.
