Contradiction in reference manual K02P64M100SFARM

Hi all,

 

I'm using a MK02FN64VFM10 and want to use a 25 MHz external crystal.

In reference manual K02P64M100SFARM, on page 503: 26.5 External Crystal / Resonator Connections it says:

 

"When using low-frequency, low-power mode, the only external component is the crystal or ceramic resonator itself. In the other oscillator modes, load capacitors (Cx , Cy ) and feedback resistor (RF) are required."

 

I conclude from this that Cx, CY and RF are always *required*, with LF-LP being the *only* exception...

 

But the table on the same page suggests that for HF-LP, the "crystal only" configuration can also be used....

 

Can someone please clarify this?

 

Regards,
