Set Duplex Mode
DescriptionValue
Enables the Full-Duplex mode of operation. This bit can be set
by software in a manual configuration process or by the
auto-negotiation process.
1
Enables the Half-Duplex mode of operation.
Note that in 10BASE-T half-duplex mode, the transmitted data
is looped back on the receive path.

Collision Test
DescriptionValue
Enables the Collision Test mode of operation.1
No effect.0
The COLT bit is set after the initiation of a transmission and is cleared
once the transmission is halted.
0R/WCOLT7
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
These bits should always be written as zero.
