    The Receiver is a fully differential circuit and can be used double ended or single ended:

    For single ended use (Quasi- Differential) of the receiver circuit it is strongly recommended to connect RxN and RxP to each other or to connect them by using the Rcv_Reg register (address 38h).But if the Rcv_Rx_single bit in the Rcv_Reg register is set to 1 -> Quasi-Differential, the unused Rx pin has to be open and not connected to Ground.

    For double ended use connect RxN and RxP, as recommended, to the
    transmitter circuit, directly after the EMC filter.
