ADF7021 vs ADF7021-N register differences

Hello,

Beyond the Register 1 changes required based on the output frequency, are there any other register differences between the ADF7021 and ADF7021-N?  I am trying to use the same register settings to support both the ADF7021 and ADF7021-N parts.  Is there an application note highlighting any differences.  I saw two differences between the datasheets (Register 3 and Register 14), but these look like clerical errors in the ADF7021 datasheet.

Thanks,

Ali
