PIC Reference Clock Module Buffer (SOLVED)

[jpanhalt]

(SOLVED)

I am considering using the reference clock of a PIC12F1840 to drive another (mid-range) PIC as an external clock source. Duty cycle is 50%; divider is currently set to 32.

Is a buffer advised or required?

For synchronization of the chips, should the buffer be inverted or in phase? The datasheet shows an inverter when using a generic external clock source but is silent on this specific application. Since my source for the reference clock is the system clock, it seems to me that inverting the reference clock would put the second chip out of phase. I don't believe the phase relationship will be important. I would just like some clarity on that decision should I need synchronization.
