No Equalization Needed Received (NOEQR)

When Set, this Port either received a Modified TS1/TS2 with the No Equalization Needed bit Set or received a non-modified TS1/TS2 was recieved with the No Equalization Needed encoding (also reported in the Received Enhanced Link Behavior Control field).

Default is 0b.

RO/V

Transmitter Precode Request (TXPRECODER)

When Set, this Port will request the transmitter to use Precoding by setting the Precoding Request bit in the TS1s/TS2s it transmits prior to entry to Recovery.Speed Default is Implementation Specific.

RO/V

Transmitter Precoding On (TXPRECODEO)

This field indicates whether the Receiver asked this transmitter to enable Precoding.

This bit is cleared on DL_​Down .

Received Enhanced Link Behavior Control (RCVDELBCTL)

This field contains the Enhanced Link Behavior Control bits from the most recent TS1 or TS2 received in the Polling or Configuration states.

This field is Cleared on DL_​Down .

RO/V

Modified TS Received (MODTSRCVD)

If Set, Received Modified TS Data 1 Register and Received Modified TS Data 2 Register contain meaningful data.

This bit is Cleared when the Link is Down. This bit is Set when the Modified TS1/TS2 Ordered Set is received

Link Equalization Request 32.0 GT/s (LERG5)

This bit is Set by hardware to request the 32.0 GT/s Link equalization process to be performed on the Link.



For a Multi-Function Upstream Port, this bit must be implemented in Function 0 and RsvdZ in other Functions.
