LM3S8971 Microcontroller
The IEEE 802.3 standard specifies a register set for controlling and gathering status from the PHY.
The registers are collectively known as the MII Management registers and are detailed in Section
22.2.4 of the IEEE 802.3 specification. Table 16-2 on page 419 also lists these 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.
