'[PIC]: accidentally used 10MHz'

Would the PIC16F84 be damaged if I used 10MHz oscillator if the maximum
allowable frequency is only 4MHz?

No, but it may not work reliably at 10MHz and will draw more current.

Not very likely. It just might not work with the 10MHz osc. You should be
able to go back to the 4MHz osc with no problems.

(btw: lets not turn this thread into another discussion of overclocking
PICs, please!)

Unlikely it would be damaged.

No damage, but even if it seems to work, don't try it.
You have enough problems to get through already.
Stick to what you KNOW will work.

Well... a 8 months ago, I have used a 4MHz PIC16F84 with a crystal
of 6.114 MHz. It works OK for long time(two weeks about).
But, when I tried to re-programm
the chip, it was impossible and the chip remains unusable (al locations
reads as 0x000 and "disable code protection" and "bulk erase" dont work).

Any other has experiences with overclocking? :-)

Cheers!
