MC9S12NE64 and the IEEE 802.3 Standard
MC9S12NE64 and the IEEE 802.3 Standard
The MC9S12NE64 Ethernet controller is compliant with the IEEE 802.3 standard and the 802.3, 802.3u,
and 802.3x specifications, so operation can be either 10 Mbps full-duplex, 10 Mbps half-duplex, 100 Mbps
full-duplex, or 100 Mbps half-duplex using a medium-independent interface (MII). Flow control and auto-
negotiation are also available.
The IEEE 802.3 specifications that are relevant to the MC9S12NE64 design include:
The MC9S12NE64 commitment to compliance is also demonstrated through its IEEE 802.3 conformance
and interoperability testing at the University of New Hampshire InterOperability Lab's (UNH IOL) Fast
Ethernet Consortium. This consortium tested the MC9S12NE64 MAC and PHY against the IEEE 803.2
design specification criteria to ensure that the Ethernet design is both correct and robust. The testing
gives assurance that the MC9S12NE64 is fully functional and, more important, interoperates with other
network devices from other manufacturers.
