100VG-AnyLAN Training

If the training frame passes these criteria, it is valid. The driver updates a counter showing the number of consecutive valid training frames passed. The driver also keeps a separate counter showing how many frames are left in the training window.

If the training frame does not pass the criteria, it is invalid. The driver must use the counter which shows how many frames are left in the training window, and if it is equal to or greater than 24, it restarts the exchange of frames.

If the training window does not allow the exchange of 24 frames, the driver must request a new training window. This can be accomplished by:

-Setting the TRFAIL bit and clearing the TRIDLE bit in the TLPHY_ctl register

-Waiting for a status interrupt. A deadman timer (10 s) may be necessary to ensure that the driver does not sit indefinitely in this state

-Checking the RETRAIN bit in TLPHY_sts when status interrupt arrives

-Requesting the beginning of the training period by clearing the TRFAIL bit and asserting the TRIDL bit in the TLPHY_ctl register

If the driver has successfully trained, the driver clears the TRIDLE bit in TLPHY_ctl and exits the training routine. You must reinitialize the AREG0 reg- ister to this adapter's address, the HASH registers, and the CAF, CSF, and NOBRX in the NetCmd register to their chosen values.
