Pause ability-C0 On
Off
Depends upon MAC. Local device pause capability C2:0 = D12:10 of
AN word.
C0 is the same as PAUSE.
Pause ability-C1 On
Off
Depends upon MAC. Local device pause capability C2:0 = D12:10 of
AN word.
C1 is the same as ASM_DIR.
Enable Link Training On
Off
Enables or disables the Link Training feature.
Maximum bit error count 15, 31, 63,
127, 255,
511, 1023
Specifies the number of bit errors for the error counter expected
during each step of the link training. If the number of errors exceeds
this number for each step, the core returns an error. The number of
errors depends upon the amount of time for each step and the
quality of the physical link media.
The default value is 511.
Number of frames to send
before sending actual data
127, 255 This timer is started when the local receiver is trained and detects
that the remote receiver is ready to receive data. The local physical
medium dependent (PMD) layer delivers wait_timer additional
training frames to ensure that the link partner correctly detects the
local receiver state.
The default value is 127.

VPOSTRULE
0-38
Specifies the maximum value that the internal algorithm for pre-
emphasis tests in determining the optimum post-tap setting. The
default value is 25.
VPRERULE
0-31
Specifies the maximum value that the internal algorithm for pre-
emphasis will ever test in determining the optimum pre-tap setting.
The default value is 16.
PREMAINVAL Preset VOD
tap Value
0-31
Specifies the Preset V
OD
value. This value is set by the Preset
command of the link training protocol, defined in Clause
72.6.10.2.3.1 of the Link Training protocol. This is the value from
which the algorithm starts. The default value is 30.
PREPOSTVAL
0-31
Specifies the preset Post-tap value. The default value is 0.
