This strap also affects the default value of the following regis-

ter bits (x=B):

• Speed Select LSB (PHY_SPEED_SEL_LSB) and Duplex

Mode (PHY_DUPLEX) bits of the PHY x Basic Control

• 10BASE-T Full Duplex and 10BASE-T Half Duplex bits of

the PHY x Auto-Negotiation Advertisement Register

(PHY_AN_ADV_x)

• PHY Mode (MODE[2:0]) bits of the PHY x Special Modes

Note:

This has no effect when the PHY is in 100BASE-FX

mode.
