Note 13.29

The reserved bits 31-16 are used to pad the register to 32-bits so that each register is on

a DWORD boundary. When accessed serially (through the MII management protocol), the

Note 13.30

The Virtual PHY does not support next page capability. This bit value will always be 0.

Note 13.31

The Remote Fault bit is not useful since there is no actual link partner to send a fault to.

Note 13.32

The Pause bit defaults to 1 if the manual_FC_strap_mii strap is low, and 0 if the

manual_FC_strap_mii strap is high. Configuration strap values are latched upon the de-

assertion of a chip-level reset as described in Section 4.2.4, "Configuration Straps," on

page 45.

Note 13.33

Virtual 100BASE-T4 is not supported.

Note 13.34

The Virtual PHY supports only IEEE 802.3. Only a value of 00001b should be used in this

field.
