DESCRIPTION
1 = software reset. Bit is self-clearing. For best results,
when setting this bit do not set other bits in this
register. The configuration (as described in
Section 5.3.9.2) is set from the register bit values,
and not from the mode pins.
1 = loopback mode,
0 = normal operation
1 = 100Mbps,
0 = 10Mbps.
Ignored if Auto Negotiation is enabled (0.12 = 1).
1 = enable auto-negotiate process
(overrides 0.13 and 0.8)
0 = disable auto-negotiate process
1 = General power down mode,
0 = normal operation
1 = electrical isolation of transceiver from MII
0 = normal operation
1 = restart auto-negotiate process
0 = normal operation. Bit is self-clearing.
1 = Full duplex,
0 = Half duplex.
Ignored if Auto Negotiation is enabled (0.12 = 1).
1 = enable COL test,
0 = disable COL test
