		TNETE211 Register Descriptions
Table B±2. PHY Generic Status Register Bits (Continued)

Bit	Name	Function

4	RFLT	Remote fault: When this bit is set, it indicates that a remote fault condition has been
		detected. This bit is autoclearing, and a remote fault condition is latched (held) until
		the register is read.
3	0	Autoconfiguration capable: Not supported
2	LINK	Link status: When this bit is read as 1, it indicates that the PHY has determined that
		a valid link has been established. When read as 0, it indicates that the link is not valid.
		This bit is autoclearing, and a link invalid state is latched (even if the link returns) until
		the register is read. This is to ensure that the driver can determine the type of MII inter-
		rupt.
1	JABBER	Jabber detect: When read as 1, this bit indicates a jabber condition has been detected.
		This bit is autoclearing, and a jabber condition is latched (held) until the register is read.
0	1	Extended capability: This bit is hardwired to 1 to indicate that the extended register set
		is supported.

B.2.3 PHY Generic Identifier±GEN_id_hi/GEN_id_lo @ 0x2/0x3

These two hardwired 16-bit registers contain an identifier code for the ThunderLAN 100VG-AnyLAN demand priority PHY. The actual value is 0x4000/ 0x502x for this PMI device, where x denotes the PHY revision.

B.2.4 ThunderLAN PHY Identifier High/Low±TLPHY_id @ 0x10

This hardwired 16-bit register contains a Texas Instruments-assigned identifi- er code for the ThunderLAN PHY/PMIs. An additional identifier is required to identify non-802.3 PHY/PMIs, which are not otherwise supported by the 802.3u MII specification. The value for the 100VG-AnyLAN demand priority is 0x0002.
