Description
Read/Write
Read will return 0, writes will be ignored.
Read Only
Read will return 1, writes will be ignored
Read Only
Read will return 0, writes will be ignored
Read Only
Read will return 0, writes will be ignored
Read Only
Read will return 0, writes will be ignored
Read Only
Read will return 0, writes will be ignored
Read Only
Read will return 0, writes will be ignored
Read Only
Read will return 1 indicating extended status information is held in
register 0x0F.
Read Only
Read will return 0, writes will be ignored
Read Only
Read will return 1 indicating the capability to accept a MDIO
command without preceding preamble. Writes will be ignored .
Read Only
Read will return the status if Auto Negotiation is completed.
Read Only
0 = AN not completed
1 = AN has been completed successful
Not Applicable. Read will return a 0.
Read Only
Read will return 1, indicating, that device is able to perform a Auto
Negotiation, writes will be ignored
Read Only
Read will return the Link Status of the selected channel past auto
negotiation has completed according to IEEE 802.3z clause 37 in
1000Base-X mode.
Read Only/
Latched Low
Will return the Link Status of the link monitor state machine when in
100Base-FX mode.
Note, the link status will always indicate high when in deep loopback
or shallow loopback. In remote loopback mode, the bit represents the
normal bit function.
1 = Link UP
0 = Link DOWN
Read will return 0, writes will be ignored
Read Only
Read will return 1 indicating extended register capability
Read Only
The identifier code is composed of bits 3-24 of the 25-bit organizationally unique identifier (OUI) assigned to
Texas Instruments by the IEEE. The 6-bit Manufacturer Model Number is unique to the TLK2226. The
Manufacturer Revision Number denotes the current revision of the TLK2226.
