Yes,

So as you can see, one crystal is compulsory, while the other one is optional and if precision, timing and power savings are your major concern, I would recommend using both the crystals. But if you are looking for cost savings, then leave out the optional crystal.

Hi Marcos,

As seen from the reference diagram, one external 32MHz is required, but the other one is optional (you can skip this if you wish). You can see the benefits of using an external 32MHz here.
