PRODUCTION DATA
Near-End Loopback provides the ability to loop the transmitted data back to the receiver via the digital or analog circuitry. The point at which the signal is looped back is selected using loopback control bits[3:0] in the BISCR register. Auto-Negotiation and Auto-MDIX should be disabled before selecting the Near-End Loopback modes. This constraint does not apply for external-loopback mode.
