BITS
DESCRIPTION
5 10BASE-T Half Duplex
This bit determines the advertised 10BASE-T half duplex capability.
0: 10BASE-T half duplex ability not advertised
1: 10BASE-T half duplex ability advertised
4:0 Selector Field
This field identifies the type of message being sent by Auto-Negotiation.
00001: IEEE 802.3
TYPE
R/W
DEFAULT
1b
R/W
00001b
Note 13.34
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
register is 16-bits wide.
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 13.32The Symmetric Pause and Asymmetric Pause bits default to 1 if the manual_FC_strap_0
strap is low (both Symmetric and Asymmetric are advertised), and 0 if the
manual_FC_strap_0 strap is high (neither Symmetric and Asymmetric are advertised).
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.
