Sharing Crystal with 2 IC's

[Darrel Taylor]

I did find one article that said it should be in series, X2 to X1 and nothing connected to X2 of the last IC in the series

That's how it should be.

1 chip has the crystal and capacitors on both X1 and X2.
X2 from the chip with the crystal goes to X1 of the other chip.
X2 of the second chip will be unused.
