:
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.
This pin is provided with an internal pull-down.

-1 PRBS Pattern Validation Error
Hardware Mode
Indicates an error condition has occurred/is
occuring in the validation of generated PRBS pattern.
"Low" = Un-erred transmission and reception of PRBS pattern.
"High" = Error Condition occurrence.
Host Mode
This pin is functions as the microprocessor Serial
Data Output.

Serial Remote Loopback
Normal Mode
The serial remote loopback mode interconnects
the receive serial data input to the transmit serial data output. If
serial remote loopback is enabled, the 16-bit parallel transmit
data input is ignored while the 16-bit parallel receive data output
and parallel receive clock output is maintained.
"Low" = Serial Remote Loopback Mode Enabled
"High" = Disabled
PRBSTest Mode
When PRBS_EN is asserted, this bit is used
to clear or reset PRBS_ERR error condition. Serial Remote
Loopback is not available in PRBS Test Mode.
"Low" = Clears PRBS_ERR condition
"High" = Normal Mode
This pin is provided with an internal pull-up.
