NLOOP is disabled upon reception of the 001 pattern for five seconds, or by activating
RLOOP or ALOOP , or by disabling NLOOP detection. Note that the LXT360 Transceiver
enters Dual loopback mode (DLOOP) when both NLOOP and LLOOP functions are
selected.

LLOOP pins High. In Host mode set bits CR2.ERLOOP = 1 and CR2.ELLOOP = 1. In
DLOOP mode, the transmit clock and data inputs (TCLK and TPOS/TNEG or TDATA) loop
back through the Jitter Attenuator (unless disabled) to RCLK and RPOS/RNEG or RDATA.
The data and clock recovered from the twisted-pair line loop back through the transmit
circuits to TTIP and TRING without jitter attenuation.
