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
