-1 PRBS Pattern Invert
This bit will invert each of the Pseudo Random Binary Sequence
pattern bit from "0" to "1" and from "1" to "0."
"0" = Normal Operation
"1" = PRBS bit patterns inverted.

N
OTE
:
A Local Loopback of some type such as Digital Local
Loopback or an optical cable loopback is expected to be
used in conjunction with PRBS_EN in order for the PRBS
analyzer to receive the PRBS pattern.

DLOOP
Digital Local Loopback
Digital local loopback allows the transmit input pins to be looped
back to the receive output pins for local diagnostics. The transmit
serial data output is valid during the digital loopback.
"0" = Enable Digital Local Loopback
"1" = Disabled
N
OTE

RLOOPS and RLOOPP should be
disabled
when DLOOP
is enabled.
