RadioThorium External Reference

Question on using an external reference with RadioThorium. Can you outline the necessary steps to switch from the internal 10 MHz reference to an external reference of a different frequency?

The API instruction set does provide some options for a change of reference frequency. But can you give an example of how we can change the LOCLK source from 10 MHz to 20 MHz?

I'm guessing that LOCLK:SEL 0 TX EXT should be first, then LOCLK:REF 0 TX EXT needs to also be set.

Can you confirm this, and tell me what other settings need to be modified to relock the PLL to the external frequency?
