I don't know whether the oscillators in other PICs are the same, though... So if you try it and the oscillator doesn't start up, you'll need to buffer the CLKOUT signal on its way to the second PIC. -Andy === Andrew Warren -- aiw@cypress.com === Principal Design Engineer === Cypress Semiconductor Corporation === === Opinions expressed above do not === necessarily represent those of === Cypress Semiconductor Corporation -- http://www.piclist.com hint: The PICList is archived three different ways.
