Receive External Fixed Resistor
RxRES[1:0] are used to select the value for a high precision
external resistor to improve return loss.
00 = None
01 = 240 Ω
10 = 210 Ω
11 = 150 Ω
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".
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".
Transformer Ratio Select:
In the external termination mode, writing a “1” to this bit selects a
transformer ratio of 1:2 for the transmitter. Writing a “0” sets the
transmitter transformer ratio to 1:2.45. In the internal termination
mode the transmitter transformer ratio is permanently set to 1:2
and the state of this bit has no effect.
