10.5.1 Loopbacks
There are several loopback paths available. The following table lists the loopback modes available for analog
loopback (ALB), line loopback (LLB), payload loopback (PLB) and diagnostic loopback (DLB). System loopback
(SLB) does not interact with these loopbacks and is given its own control bit. The LBM bits are located in
PORT.CR4.
