TxOn
Transmit ON/OFF
Upon power up, the transmitters are powered off. This bit is used
to turn the transmitter for this channel On or Off if the TxON pin is
pulled "High". If the TxON pin is pulled "Low", all 14 transmitters
are powered off.
0 = Transmitter is Powered OFF
1 = Transmitter is Powered ON

INSBPV
Insert Bipolar Violation
When this bit transitions from a "0" to a "1", a bipolar violation will
be inserted in the transmitted data from TPOS, QRSS/PRBS pat-
tern. The state of this bit will be sampled on the rising edge of
TCLK. To ensure proper operation, it is recommended to write a
"0" to this bit before writing a "1".
