QRSS/PRBS Select Bits
These bits are used to select between QRSS and PRBS.
0 = PRBS_n (215 - 1)
1 = QRSS_n (220 - 1)

PRBS Receive/Transmit Select:
This bit is used to select where the output of the PRBS Generator is
directed if PRBS generation is enabled.
0 = Normal Operation - PRBS generator is output on TTIP and
TRING if PRBS generation is enabled.
1 = PRBS Generator is output on RPOS and RCLK.

Receiver ON:
This bit permits the user to either turn on or turn off the Receive Sec-
tion of XRT86VL30. If the user turns on the Receive Section, then
XRT86VL30 will begin to receive the incoming data-stream via the
RTIP and RRING input pins.
Conversely, if the user turns off the Receive Section, then the entire
Receive Section except the MCLKIN Phase Locked Loop (PLL) will
be powered down.
0 = Shuts off the Receive Section of XRT86VL30.
1 = Turns on the Receive Section of XRT86VL30.
