Changing to "_XT_OSC" has activity at the crystal as well as _HS_OSC did with the same result that pulling the crystal makes no difference, the code runs no matter.

Make sure your programmer is updating the CONFIG settings of the chip.
Usually there's an option for that.
It may still be using the CONFIG settings from a previous program.

Hi Bob,
This particular PIC has special Oscillator, options and Has FSCM, which stands for Fail Safe Clock Monitor - datasheet page 49 of 294 and as I understand it, it automaticly deploys an internal clock when oscillator failure occurs, pretty darn nifty feature unless you are doing what You want to . Easiest way is use a cheaper PIC.
If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

And never learn... not for me.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Me no understand . . . was I wrong?

'The Easiest solution and use another PIC' reply always drive me nuts when the user don't need to and have a nice 'learning opportunitie' on hand... i know i may have badly interpret it anyways... Need to sleep... sorry
Good news, you are right! Assuming the Fail-Safe clock monitor AND the int-ext-switchover mode are both enable, at POR, the internal OSC run @ 4MHz.... hence why it always work without noticeable bugs.

Ah, thanks to Joe S. for the info. I have verified this by using a 4.91 Mhz crystal, far enough out to show errors in frequency counting.
Pulling the crystal had the PIC instantly switch to it's internal RC source. THANKS!

ICE e e e e gotit EWE SCAERT MEE . . thought I missed something in de datasheet, possible as it was about 4 am here when I wrote that.may bee hi deed not reed care foolee dee hole tred
