 		 #172734 - Richard is right...
Responding to: Erik Malund's previous message
Erik said:
if all you are driving is the actual uC, there is no need whatsoever for an external oscillator.

If I had to clock this AT89S51 at 33MHz, I would also use an oscillator modul very probably, because these ATMEL's built-in Pierce oscillators don't work very well at such high frequencies. I have heard lots of complaints in the past. So, Richard isn't that wrong.

Erik, Richard, what would this forum be without your amusing foot fights...
