    Interrupt (INTRP)
    INTRP (pin 21) is an optional interrupt signal that is used to inform the external controller that there has been a status
    update to the KSZ8051MNL/RNL PHY register. Register 1Bh, bits [15:8] are the interrupt control bits to enable and
    disable the conditions for asserting the INTRP signal. Register 1Bh, bits [7:0] are the interrupt status bits to indicate which
    interrupt conditions have occurred. The interrupt status bits are cleared after reading register 1Bh.
    Register 1Fh, bit 9 sets the interrupt level to active high or active low. The default is active low.
    The MII management bus option gives the MAC processor complete access to the KSZ8051MNL/RNL control and status
    registers. Additionally, an interrupt pin eliminates the need for the processor to poll the PHY for status change.
    HP Auto MDI/MDI-X
    HP Auto MDI/MDI-X configuration eliminates the confusion of whether to use a straight cable or a crossover cable
    between the KSZ8051MNL/RNL and its link partner. This feature allows the KSZ8051MNL/RNL to use either type of cable
    to connect with a link partner that is in either MDI or MDI-X mode. The auto-sense function detects transmit and receive
    pairs from the link partner, and then assigns transmit and receive pairs of the KSZ8051MNL/RNL accordingly.
    HP Auto MDI/MDI-X is enabled by default. It is disabled by writing a one to register 1Fh, bit 13. MDI and MDI-X mode is
    selected by register 1Fh, bit 14 if HP Auto MDI/MDI-X is disabled.
    An isolation transformer with symmetrical transmit and receive data paths is recommended to support auto MDI/MDI-X.
    The IEEE 802.3 Standard defines MDI and MDI-X as follows:
    MDI
    MDI-X

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