HP Auto Crossover (Auto MDI/MDI-X)
Automatic MDI/MDI-X configuration is intended to eliminate the need for crossover cables between similar devices. The assignment
of pin-outs for a 10/100 BASE-T crossover function cable is shown below.
This feature can eliminate the confusion in real applications by allowing both straight cable and crossover cables. This feature is
controlled by register 1f:13, see “Register 1fh” section for details.
