Bit 5: Receive Fail 2 Enable (RFL2E).
This bit is used to enable the receive failure type 2 detection. See Section
0 = Disable receive failure type 2 detection
1 = Enable receive failure type 2 detection
Bit 4: Receive LIU Monitor Mode (RMON).
This bit is used to enable the receive LIU monitor mode preamplifier.
Enabling the preamplifier adds about 14dB of linear amplification for use in monitor applications where the signal
has been reduced 20dB using resistive attenuator circuits. Note: When enabled, the preamp is turned on or off
automatically depending upon the input signal level. See Section 8.3.2.
0 = Disable the preamp
1 = Enable the preamp
Bit 3: Receive Termination Resistor Enable (RTRE).
This bit indicates when the receiver internal termination is
enabled. See Section 8.3.1.
0 = Disabled, the receiver is terminated externally
1 = Enabled, the receiver is terminated internally
Bits 2 to 0: Receive Resistor Adjustment (RRESADJ[2:0]).
These bits are used to adjust the internal termination
resistance of the receiver. See Section 8.3.1.
