Bits Name
9 Speed[1] Speed selection. This bit defaults to a set state and should always be set, which corresponds to 1000 Mbps
speed.Setting this field controls the speed at which the TBI operates. The following table provides the
appropriate encoding. Its default is bit[2] = '0'; bit[9] = '1'.

Bits Name
0–6 — Reserved, should be cleared.
7 Extend This bit indicates that PHY status information is also contained in the Register 15, Extended Status Register.
Status Returns 1 on read. This bit is read-only.
8 — Reserved, should be cleared.
9 No MF preamble suppression enable. This bit indicates whether or not the PHY is capable of handling MII
Pre management frames without the 32-bit preamble field. Returns 1, indicating support for suppressed
preamble MII management frames. This bit is read-only.
10 AN Auto-negotiation complete. This bit is read-only and is cleared by default.
Done 0 Either the auto-negotiation process is underway or the auto-negotiation function is disabled.
1 The auto-negotiation process has completed.
11 Remote Remote fault. This bit is read-only and is cleared by default. Each read of the status register clears this bit.
Fault 0 Normal operation.
1 A remote fault condition was detected. This bit latches high in order for software to detect the condition.
