LM3S6950 Datasheet, PDF (370/524 Pages) List of Unclassifed Manufacturers – Microcontroller

Ethernet Controller
22.2.4 of the IEEE 802.3 specification. Table 15-2 on page 370 lists the MII Management registers.
All addresses given are absolute and are written directly to the REGADR field of the MACMCTL
register. The format of registers 0 to 15 are defined by the IEEE specification and are common to
all PHY implementations. The only variance allowed is for features that may or may not be supported
by a specific PHY. Registers 16 to 31 are vendor-specific registers, used to support features that
are specific to a vendors PHY implementation. Vendor-specific registers not listed are reserved.
