Data Sheet
6.10.1.7. RF PLL Trim
This register contains the value of the trim from the self calibration. The values written to this register by the PLL calibration can provide
some indication of the quality of the frequency selection. Values at the maximum or minimum allowed for the TX or RX trim function,
even when calibration passes, may indicate (although not necessarily) that a different value for the VCO external LC components could
provide better performance or that a slightly different frequency should be used.
