Parallel Loopback
The parallel loopback mode exercises the digital logic portion of the
transceiver data path. The analog portions are not used in this loopback
path, and the received high-speed serial data is not retimed. This protocol
is available as one of the sub-protocols under Basic mode and can be used
only for Basic double-width mode.
In this loopback mode, the data from the internally available BIST
generator is transmitted. The data is looped back after the end of PCS and
before the PMA. On the receive side, an internal BIST verifier checks for
errors. This loopback enables you to verify the PCS block.
