    Ethernet: Three-Speed, MII Management
    This section provides the AC and DC electrical characteristics forthree-speed, 10/100/1000, and MII
    management.
    8.1
    Three-Speed Ethernet Controller (TSEC)
    (10/100/1000 Mbps)—GMII/MII/TBI/RGMII/RTBI Electrical
    Characteristics
    The electrical characteristics specified here apply to allGMII (gigabit media independent interface), the
    MII (media independent interface), TBI (ten-bit interface), RGMII (reduced gigabit media independent
    interface), and RTBI (reduced ten-bit interface) signals except MDIO (management data input/output) and
    MDC (management data clock). The RGMII and RTBI interfaces are defined for 2.5 V, while the GMII
    and TBI interfaces can be operated at 3.3 or 2.5 V. Whether theGMII, MII, or TBI interface is operated at
    3.3 or 2.5 V, the timing is compliant with the IEEE 802.3 standard. The RGMII and RTBI interfaces follow
    the Hewlett-Packard reduced pin-count interface for Gigabit Ethernet Physical Layer Device Specification
    Version 1.2a (9/22/2000). The electrical characteristics for MDIO and MDC are specified in Section 8.3,
    8.1.1
    TSEC DC Electrical Characteristics
    All GMII, MII, TBI, RGMII, and RTBI drivers and receivers comply with the DC parametric attributes
    specified in Table 18 and Table 19. The potential applied to the input of a GMII, MII, TBI, RGMII, or
    RTBI receiver may exceed the potential of the receiver’s power supply (i.e., a GMII driver powered from
    a 3.6-V supply driving VOH into a GMII receiver powered from a 2.5-V supply). Tolerance for dissimilar
    GMII driver and receiver supply potentials is implicit in these specifications. The RGMII and RTBI signals
    are based on a 2.5-V CMOS interface voltage as defined by JEDEC EIA/JESD8-5.

    Notes:
    1. Actual attainable baud rate will be limited by the latency of interrupt processing.
    2. The middle of a start bit is detected as the 8th sampled 0 after the 1-to-0 transition of the start bit.
    Subsequent bit values are sampled each 16th sample.
    3. Guaranteed by design.
