Hi guys, Thanks for your answers, I think I'll stay away from overclocking this PIC (even if hobby, as Vasile's nose smelt it despite the numerous kilometers :)
I was hoping to use it in a Jaluino board, instead of 18f4550, even if loosing USB. Jaluino has a 20 MHz external crystal, so my previous question. I could run 18f46k20 at 20 MHz (no PLL), but I could also use internal OSC and run it at 16 * 4 = 64 MHz. The problem is I don't want to solder/unsolder the crystal. What if I keep it on the board, but use internal OSC ? Would it cause troubles ? Maybe setting corresponding pins to output ?
