Memory Map and Register Descriptions
100XHD —100BASE-TX Half-Duplex
1 = Indicates the PHY supports 100BASE-TX half-duplex mode
0 = Indicates the PHY does not support 100BASE-TX half-duplex mode
10TFD —10BASE-T Full-Duplex
1 = Indicates the PHY supports 10BASE-T full-duplex mode
0 = Indicates the PHY does not support 10BASE-T full-duplex mode
10THD —10BASE-T Half-Duplex
1 = Indicates the PHY supports 10BASE-T half-duplex mode
0 = Indicates the PHY does not support 10BASE-T half-duplex mode
SUPPRE —MF Preamble Suppression
1 = Indicates that management frames are not required to contain the preamble stream
0 = Indicates that management frames are required to contain the preamble stream
ANCOMP —Auto-Negotiation Complete
To inform the management interface (MI) that it has completed processing, ANCOMP is set by the
A/N process. After it has been started, the auto-negotiation process uses link code words to exchange
capability information and establish the highest common denominator (HCD) for link transactions.
1 = Indicates that the auto-negotiation process has completed and that the contents of registers 4
through 7 are valid.
0 = Indicates that the auto-negotiation process has not completed and that the contents of registers
4 through 7 are not valid
REMFLT — Remote Fault
Possible remote faults (RF)
a) The link partner transmits the RF bit (5.13=1)
b) Link partner protocol is not 00001 (5.4:0)
c) Link partner advertises only T4 capability (5.9:5)
d) No common operation mode found between PHY and the link partner.
After it is set, REMFLT is cleared each time register 1 is read via the management interface. REMFLT
is also cleared by a PHY reset.
1 = Indicates that a remote fault condition has been detected.
0 = No fault detected
ANABL — Auto-Negotiation Ability
1 = Indicates that PHY has auto-negotiation ability
0 = Indicates that PHY does not have auto-negotiation ability
LNKSTST — Link Status
The PHY sets this bit when it determines that a valid link has been established. The occurrence of a
link failure will cause LNKSTST to be cleared. After it has been cleared, it remains cleared until it is
read via the management interface.
1 = Indicates a valid link has been established
0 = Indicates a valid link has NOT been established
