There is a way to combine the DLD and the LREF into a single signal at the STATUS pin. Set 08h<5:2> = <1101b> to get a signal that is the logical OR of the loss-of-lock (inverse of DLD) and the loss-of-reference (LREF) active high. If an active low version of this same signal is desired, set 08h<5:2> = <1110b>.
