      Hi All

       

      Hopefully this isn't covered elsewhere, but I've spent some time searching and had no luck.

       

      I have a device with a 24MHz xtal and would like to change this to an external 3.3v oscillator.  I notice from the manual that XTALIN doubles up as an xtal input and external 3.3v square wave clock.

       

      My question is this:  Can I simply remove the 24MHz xtal and capacitors and connect an external clock to XTALIN with no firmware mods?  Does the pin function change automatically?

       

      Thanks for reading.....
