82577 GbE PHY—Programmer’s Visible State
1b = Enables Carrier Sense Indication (CRS)
on transmit in half-duplex mode.
0b = Disables CRS on transmit.

00b = +/-8.
01b = +/-16.
10b = +/-24.
11b = +/-32.
If automatic downshift is enabled and the
PHY fails to auto-negotiate at 1000BASE-T,
the PHY falls back to attempt connection at
100BASE-TX and, subsequently, 10BASE-T.
This cycle repeats. If the link is broken at any
speed, the PHY restarts this process by re-
attempting connection at the highest possible
speed (1000BASE-T).
00b = Automatic speed downshift disabled.
01b = 10BASE-T downshift enabled.
10b = 100BASE-TX downshift enabled.
11b = 100BASE-TX and 10BASE-T enabled.
Reserved
1b = Enables manual control of 1000BASE-T
next pages only.
0b = Normal operation of 1000BASE-T next
page exchange.
1b = Enables group MDIO mode.
0b = Disables group MDIO mode.
When this bit is set, the transmit test clock is
available on pin TX_TCLK.
1b = Enables output of mixer clock (transmit
clock in 1000BASE-T).
0b = Disables output.
