3.10. Auxiliary Output (AUXOUT)
The signal appearing on AUXOUT is selected by setting the AUXSEL bits in the Main Configuration register
(Register 0).
The LDETB signal can be selected by setting the AUXSEL bits to 11. This signal can be used to indicate that the IF
or RF PLL is going to lose lock because of excessive ambient temperature drift and should be re-tuned. The
LDETB signal indicates a logical OR result if both IF and RF are simultaneously generating a signal.
