| When adaptation is enabled, the 10GBASE-KR link training may not finish in the required 500 ms. This results in a Link Training Failure. When this occurs, equalization may not be trained optimally for the link. |
You can disable adaptation and use a fixed CTLE value during link training. This is done by setting 0x4D0[22:20] to 4, and 0x4D0[28:24] to the desired CTLE value. |
| The 10GBASE-KR register, 0x4d2[0] Link Trained – Receiver status, is read incorrectly as 0 when testing on HW. It will be read back correctly during simulation. |
