Restart Auto-Negotiation (PHY_RST_AN)
When set, this bit restarts the Auto-Negotiation process.
0: Normal operation
1: Auto-Negotiation restarted
Duplex Mode (PHY_DUPLEX)
This bit is used to set the duplex when the
is disabled.
0: Half Duplex
1: Full Duplex
Collision Test Mode (PHY_COL_TEST)
This bit enables/disables the collision test mode of the Port x PHY. When
set, the collision signal is active during transmission. It is recommended that
this feature be used only in loopback mode.
0: Collision test mode disabled
1: Collision test mode enabled

Note 13.55 The default value of this bit is determined by the logical OR of the Auto-Negotiation strap
Note 13.56 The default value of this bit is the value of the Auto-Negotiation strap
Note 13.57 The default value of this bit is determined by the logical AND of the negation of the Auto-

strap
Auto-Negotiation strap is set, the default value is 1, otherwise the default is determined by
the value of the Speed Select strap. Refer to

Negotiation strap
the Duplex Select strap
Essentially, if the Auto-Negotiation strap is set, the default value is 0, otherwise the default
is determined by the value of the Duplex Select strap. Refer to
