Setting this bit causes auto-negotiation to be
restarted. It is an Act-Once bit which is cleared once
auto-negotiation has begun. Clearing this bit has no
effect on the auto-negotiation process.
When bit 12 is clear, this bit controls the Full-
Duplex/Half-Duplex operation of the part. When set,
the part is configured for Full-Duplex operation, and
when clear the part is configured for Half Duplex
operation. The setting of this bit is superseded by
auto-negotiation, and thus has no effect if bit 12 is
set.
When set, the COL pin will be asserted within 10 bit
times in response to the assertion of TX_EN. Upon
the deassertion of TX_EN, COL will be deasserted
within 4 bit times. When Collision Test is clear, COL
functions normally.
