the state of 9.9 during Auto-Negotiation. After Auto-Negotiation is complete, changing the state of this bit has no effect unless
Auto-Negotiation is manually restarted.
9.8 – 1000BASE-T HDX
Since the VSC8211 is 1000BASE-T HDX capable, this bit is “1” by default. If bit 9.8 is written to be “0”, the Auto-Negotiation
state machine for the local PHY will be blocked from advertising 1000BASE-T HDX. Note that the Link Partner will be notified of
the state of bit 9.8 during Auto-Negotiation. After Auto-Negotiation is complete, changing the state of this bit has no effect unless
Auto-Negotiation is manually restarted.

In Clause-37 register view, MII register 9 is reserved. Note that MII register 9 bits in Clause-28 view remain valid, but cannot be
read or written to if the current register view is Clause-37.

The state of this register is internally latched when the Auto-Negotiation state machine enters the ABILITY_DETECT state. Changes to the
states of these bits are recognized only at that time. This register is valid only in 1000BASE-T mode.
