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
RESERVED
Note 13.51 The default value of this bit is determined by the logical OR of the Auto-Negotiation strap
Note 13.52 The default value of this bit is determined by the value of the Auto-Negotiation strap
Note 13.53 The default value of this bit is determined by the logical AND of the negation of the Auto-
(autoneg_strap_1 for Port 1 PHY, autoneg_strap_2 for Port 2 PHY) and the speed select
strap (speed_strap_1 for Port 1 PHY, speed_strap_2 for Port 2 PHY). Essentially, if the
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
page 45
(autoneg_strap_1 for Port 1 PHY, autoneg_strap_2 for Port 2 PHY). Refer to
"Configuration Straps," on page 45
Negotiation strap (autoneg_strap_1 for Port 1 PHY, autoneg_strap_2 for Port 2 PHY) and
the duplex select strap (duplex_strap_1 for Port 1 PHY, duplex_strap_2 for Port 2 PHY).
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
Straps," on page 45
