15, 31, 63, Specifies the number of bit errors for the error counter expected
127, 255, during each step of the link training. If the number of errors exceeds
511, 1023 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.
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
training frames to ensure that the link partner correctly detects the
local receiver state.
The default value is 127.

clause 73.10.2.
• 500 - 510 ms for BASE-R
• 40 – 50 ms for GbE, XAUI
The default value is 125.

emphasis tests in determining the optimum post-tap setting. The
default value is 25.
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.
Specifies the Preset V

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.
