Different PRBS patterns are available as a subprotocol under Basic functional mode
for single-width and double-width mode, as shown in the following sections.
You can enable the serial loopback option in Basic PRBS mode to loop the generated
pattern to the receiver channel. This creates a rx_seriallpbken port that you can use
to dynamically control the serial loopback. The 8B/10B encoder/decoder blocks are
bypassed in Basic PRBS mode.
