Adjusting crystal load capacitors.

I've got a custom K10 based board running well on a modified K40 BSP and PSP. I have a question relating to the Kinetis's built in load capacitors for the external crystal. I couldn't not find any location in the code where these caps are configiured. I find this odd, because the K40 Tower board that the BSP was written for doesn't include any load caps for the crystal, so it must be using the caps internal to the MCU. But where in the code are they configured?

 

My board seems to work fine, but I'd rather know where I can safely adjust the crystal's load caps to ensure I'm getting the best stability.

 

Thanks,

 

Brad
