10BASE-T Full Duplex
This bit determines the advertised 10BASE-T full duplex capability.
0: 10BASE-T full duplex ability not advertised
1: 10BASE-T full duplex ability advertised
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
Selector Field
This field identifies the type of message being sent by Auto-Negotiation.
00001: IEEE 802.3
Note 13.55 The Pause and Asymmetric Pause bits are loaded into the PHY registers by the EEPROM
Note 13.56 The default value of this bit is determined by the Manual Flow Control Enable Strap
Note 13.57 The default value of this bit is determined by the logical OR of the Auto-Negotiation strap
Note 13.58 The default value of this bit is determined by the logical OR of the Auto-Negotiation strap

(manual_FC_strap_x). When the Manual Flow Control Enable Strap is 0, this bit defaults
to 1 (symmetric pause advertised). When the Manual Flow Control Enable Strap is 1, this
bit defaults to 0 (symmetric pause not advertised). Configuration strap values are latched
upon the de-assertion of a chip-level reset as described in
