Power Management
The KS8993F features a per-port power down mode. To save power, a port that is not being used can be powered
down through the port control registers, or MIIM control registers. In addition, there is a full chip power down mode.
When activated, the entire chip will be shut down.
2.3.9
Auto MDI/MDI-X Crossover
The KS8993F supports auto MDI/MDI-X crossover. This facilitates the use of either a straight connection CAT-5 cable
or a crossover CAT-5 cable. The auto-sense function will detect remote transmit and receive pairs, and correctly
assign the transmit and receive pairs from the KS8993F device. This feature can be extremely useful when the end
users are unaware of cable type differences, and can also save on an additional uplink configuration connection.
By default, auto MDI/MDI-X is enabled. It can be disabled through the port control registers.
Based on the IEEE 802.3 standard, the MDI and MDI-X definitions are as follows:

A “Straight Cable” connects a MDI device to a MDI-X device, or a MDI-X device to a MDI device. The following diagram depicts a
typical “Straight Cable” connection between a NIC card (MDI) and a switch, or hub (MDI-X).
