Toggle:
1 = Value of toggle bit in previously transmitted Link Code Word
was logic 0.
0 = Value of toggle bit in previously transmitted Link Code Word
was logic 1.
Toggle is used by the Arbitration function within Auto-Negotiation
to ensure synchronization with the Link Partner during Next Page
exchange. This bit shall always take the opposite value of the
Toggle bit in the previously exchanged Link Code Word.
This field represents the code field of the next page transmission.
If the MP bit is set (bit 13 of this register), then the code shall be
interpreted as a "Message Page”, as defined in annex 28C of
IEEE 802.3u. Otherwise, the code shall be interpreted as an "Un-
formatted Page”, and the interpretation is application specific.
The default value of the CODE represents a Reserved for future
use as defined in Annex 28C of IEEE 802.3u.
Test Mode Select:
See IEEE 802.3ab section 40.6.1.1.2 “Test modes” for more in-
formation. Output for TX_TCLK when in Test Mode is on pin 6.
Enable Manual Master / Slave Configuration:
1 = Enable Manual Master/Slave Configuration control.
0 = Disable Manual Master/Slave Configuration control.
Using the manual configuration feature may prevent the PHY
from establishing link in 1000Base-T mode if a conflict with the
link partner’s setting exists.
Manual Master / Slave Configuration Value:
1 = Set PHY as MASTER when register 09h bit 12 = 1.
0 = Set PHY as SLAVE when register 09h bit 12 = 1.
Using the manual configuration feature may prevent the PHY
from establishing link in 1000Base-T mode if a conflict with the
link partner’s setting exists.
1 = Repeater or Switch.
0 = DTE.
(The default value of this bit is = to the strap value of pin 94 during
reset/power-on IF Auto-Negotiation is enabled.)
