The datasheet describes: "avoid RFx pins left open circuit".
Is this also valid for RFC?
Sorry for the delayed reponse, I have some issues with getting updates from the forum.
On your question, yes, you should try and minimise any floating node risks on the RFC pin as well. The risk here is around accidently hot switching the part with an unknown power if RFC its left floating and the switch is subsequenly toggled.
