Receive External Fixed Resistor
RxRES[1:0] are used to select the value for a high precision exter-
nal resistor to improve return loss.
00 = None

INSBPV
Insert Bipolar Violation
When this bit transitions from a "0" to a "1", a bipolar violation will
be inserted in the transmitted QRSS/PRBS pattern. 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".
R/W
0
D1
INSBER
Insert Bit Error
When this bit transitions from a "0" to a "1", a bit error will be
inserted in the transmitted QRSS/PRBS pattern. 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".
