ADF7021-N AFC calculation error and GMSK with UART

In the eval board software for the ADF7021-N, the calculation for AFC seems to not allow the user to specify a XTAL frequency other than the default value (In my case, 12MHz). THis give an error in the calculated AFC.

It seems to work ok for the Non-N version.

Can you please confirm this is an error?


B ) THe datasheet indicated that the ADF7021-N  cannot be used with GMSK  if you are using a UART . Why the limitation?
