Receive External Resistor Control Pin 1: In Host mode, this bit
along with the RXRES0_n bit selects the value of the external
Receive fixed resistor according to the following table;
Receive External Resistor Control Pin 0: For function of this
bit see description of D4 the RXRES1_n bit.
Insert Bipolar Violation: When this bit transitions from “0” to
“1”, a bipolar violation is inserted in the transmitted data
stream of the selected channel number n. Bipolar violation can
be inserted either in the QRSS pattern, or input data when
operating in single-rail mode. The state of this bit is sampled
on the rising edge of the respective TCLK_n.
N
Insert Bit Error: With TDQRSS enabled, when this bit transi-
tions from “0” to “1”, a bit error will be inserted in the transmit-
ted QRSS pattern of the selected channel number n. The state
of this bit is sampled on the rising edge of the respective
TCLK_n.
N
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.
