Set to 1 to put the RTL8201BL into repeater mode
Assertion of this bit allows bypassing of the 4B/5B &
5B/4B encoder.
Assertion of this bit allows bypassing of the
scrambler/descrambler.
Set to 1 to enable Link Down Power Saving mode
Set to 1 to power down analog function of transmitter
and receiver.
Detect length OK indication. Assert low to indicate
detect length OK.
LB<1:0> are register bits for loopback control as
defined below:
1) 0 0 for normal mode;
2) 0 1 for PHY loopback;
3) 1 0 for twister loopback
Used to logic force good link in 100Mbps for
diagnostic purposes.
Assertion of this bit causes a code error detection to
be reported.
Assertion of this bit causes a pre-mature end error
detection to be reported.
Assertion of this bit causes a link error detection to be
reported.
Assertion of this bit causes a detection of packet
errors due to 722 ms time-out to be reported.
Parameter access enable, set 1 to access register
