Writing a
‘
1
’
causes the port to renegotiate if its Auto-Negotiate Enable
bit is set to
‘
1
’
. Writing a
‘
1
’
to this bit overrides the port external
configuration settings.
These bits are self-clearing.

Auto-Negotiate
Enable (Port 4)
1 = Port auto negotiate is enabled.
0 = Port auto negotiate is not enabled.
Enabling auto-negotiation via software requires writing to both the Port
Speed Control Register and the Auto-Negotiate Configuration Register
(see
Table 61 on page 85
).
If Auto negotiate is not enabled, the port will take on the speed forced
values set in the port speed control register. If auto negotiate is enabled,
all abilities will be advertised. Forcing a port speed via the port speed
control register (refer to
Table 61 on page 85
) will always override and
disable auto-negotiation.
