MII Data
This field contains the value written to the PHYs. For a write operation, this
register should be first written with the desired data.
PHY Management Interface (PMI)
The PMI registers are used (by the EEPROM Loader only) to indirectly access the PHY registers.
Refer to
information on the PHY registers.
Note: These registers are only accessible by the EEPROM Loader and NOT by the Host bus. Refer
PHY Management Interface Data Register (PMI_DATA)
This register is used in conjunction with the
