7.5.4.3.1 Polling.LFPS Requirements
•Upon entry, a LFPS receiver shall be enabled to receive the Polling.LFPS signals defined in Section 6.9.1.
•Upon entry, a port shall establish its LFPS operating condition within 80 µs.
• A downstream port shall disable its transition path to Compliance Mode upon PowerOn Ret or Warm Ret.
• A downstream port shall enable its transition path to Compliance Mode, if directed.
•An upstream port always has its transition path to Compliance Mode enabled upon PowerOn Ret.
• A port in SuperSpeed operation shall transmit Polling.LFPS.
•An upstream port in SuperSpeedPlus operation shall transmit SCD1 defined in Table 6-32. If no signature of SCD1 is found in sixteen concutive Polling.LFPS received, the port shall
switch to SuperSpeed operation and transmit Polling.LFPS instead of SCD1.
• A downstream port in SuperSpeedPlus operation shall transmit SCD1 defined in Table 6-32 if Compliance Mode is disabled. If no signature of SCD1 is found in sixteen concutive
Polling.LFPS received, the port shall switch to SuperSpeed operation and transmit
Polling.LFPS instead of SCD1.
• A downstream port in SuperSpeedPlus operation shall transmit SCD2 if Compliance Mode is enabled.
•Note: In ca a retimer is connected to the downstream port, SCD2 is ud for the retimer to enable Compliance Mode. Refer to Appendix F for details.
• A port in SuperSpeedPlus operation shall implement a 60-us timer
(tPollingSCDLFPSTimeout) to monitor the abnce of LFPS signal after the completion of
SuperSpeed Polling.LFPS handshake.
• A port in SuperSpeedPlus operation shall be ready for SuperSpeed operation if it has detected that its link partner operates at SuperSpeed.
•Note: There is no time allocated for a SuperSpeedPlus port to re-configure itlf for SuperSpeed operation upon detection of its link partner operating at SuperSpeed. A
SuperSpeedPlus port shall switch to SuperSpeed operation as quickly as possible for its
receiver equalization training. Any time for configuration will result in receiving fewer TSEQ
ordered ts from its link partner.
• A port shall disable its transition path to Compliance Mode when it has successfully completed Polling.LFPS handshake or has entered Compliance Mode.
• A 360-ms timer (tPollingLFPSTimeout) shall be started upon entry to the substate.
•The operating condition of an eSS PHY shall be established when a port is ready to exit to Polling.RxEQ.
•An eSS receiver in SuperSpeed operation may optionally be enabled to receive TSEQ ordered ts for receiver equalizer training.
•Note: The port first entering Polling.RxEQ will start transmitting TSEQ ordered ts while the other port is still in Polling.LFPS. Enabling a SuperSpeed receiver in Polling.LFPS will
allow a port to start the receiver equalizer training while completing the requirement for
Polling.LFPS exit handshake.

• A downstream port shall disable its transition path to Compliance Mode upon PowerOn Ret or Warm Ret.
• A downstream port shall enable its transition path to Compliance Mode, if directed.
•An upstream port shall always have its transition path to Compliance Mode enabled upon PowerOn Ret.
• A port in SuperSpeed operation shall transmit Polling.LFPS.
•An upstream port in SuperSpeedPlus operation shall transmit SCD1 defined in Table 6-32. It shall perform in one of the following ways if no signature of SCD1 or SCD2 is detected
within the received Polling.LFPS bursts.
1.If it has received sixteen or more concutive Polling.LFPS bursts and the
tPollingSCDLFPSTimeout timer has not expired, it shall switch to SuperSpeed operation
and transmit Polling.LFPS instead of SCD1.
Note: This may imply that its SuperSpeed link partner is nsitive to varying tRepeat of
the Polling.LFPS bursts of SCD1.
2.If the tPollingSCDLFPSTimeout timer has expired, it shall switch to SuperSpeed
operation in preparation to transition to Polling.RxEQ when all exit conditions are met.
Note: This may imply that its SuperSpeed link partner may enter Polling.LFPS first, and
may be innsitive to varying tRepeat of SCD1 or SCD2, and has met all the exit
conditions to Polling.RxEQ.
• A downstream port in SuperSpeedPlus operation shall transmit SCD1 defined in Table 6-32 if Compliance Mode is disabled. It shall perform in one of the following ways if no signature
of SCD1 or SCD2 is detected within the received Polling.LFPS bursts.
1.If it has received sixteen or more concutive Polling.LFPS bursts and the
tPollingSCDLFPSTimeout timer has not expired, it shall switch to SuperSpeed operation

2.If the tPollingSCDLFPSTimeout timer has expired, it shall switch to SuperSpeed
operation in preparation to transition to Polling.RxEQ when all exit conditions are met.

SuperSpeed Polling.LFPS handshake. During this period, the port shall continue the
transmission of Polling.LFPS or SCD1 until its expiration.
• A port in SuperSpeedPlus operation shall be ready for SuperSpeed operation if it has detected that its link partner operates at SuperSpeed.

7.5.4.3.2 Exit from Polling.LFPS
•The port in SuperSpeed operation shall transition to Polling.RxEQ when the following three conditions are met:
1.At least 16 concutive Polling.LFPS bursts meeting the Polling.LFPS specification
defined in Section 6.9 are nt.
2.Two concutive Polling.LFPS bursts are received.
3.Four concutive Polling.LFPS bursts are nt after receiving one Polling.LFPS burst.
•The port in SuperSpeedPlus operation shall transition to Polling.LFPSPlus if two SCD1 are transmitted after one SCD1 or SCD2 as defined in Section 6.9.4.2 is received.
•The port in SuperSpeedPlus operation shall transition to Polling.RxEQ and switch to SuperSpeed operation if the following conditions are met:
1.At least two concutive Polling.LFPS bursts are received.
2.Twenty Polling.LFPS bursts are transmitted, and no SCD1 is detected.
Note: This condition guarantees that, in the ca of a port in SuperSpeedPlus operation
connecting to a port in SuperSpeed operation, a port in SuperSpeed operation will receive
twenty concutive Polling.LFPS to exit from this substate if it is unable to recognize
Polling.LFPS with varying tRepeat in SCD1.
3.No LFPS signal for more than tPollingSCDLFPSTimeout is obrved.
Note: This condition implies the SuperSpeed link partner has entered Polling.RxEQ
transmitting TSEQ ordered ts.
•An upstream port shall transition to Compliance Mode upon the 360-ms timer timeout (tPollingLFPSTimeout) and the following two conditions are met:
1.The port has never successfully completed Polling.LFPS after PowerOn Ret.
2.The condition to transition to Polling.RxEQ or Polling.LFPSPlus is not met.
Note: If the very first attempt in Polling.LFPS handshake fails after PowerOn Ret, it
implies that a passive test load may be prent and compliance test should be initiated. If
the very first attempt in Polling.LFPS handshake succeeds after PowerOn Ret, it
implies the prence of the Enhanced SuperSpeed ports on each side of the link and no
compliance test is intended. Therefore, any subquent handshake timeout in
Polling.LFPS when the link is retrained is only an indication of link training failure, not a
signal to enter Compliance Mode.
• A downstream port shall transition to Compliance Mode upon the 360-ms timer timeout (tPollingLFPSTimeout) if the following three conditions are met:
1.The Compliance Mode is enabled.
2.The port has never successfully completed Polling.LFPS handshake after Compliance

3.The condition to transition to Polling.RxEQ or Polling.LFPSPlus is not met.
Note: In ca Compliance mode is disabled, a downstream port may enter Rx.Detect
attempting Polling.LFPS handshake again, or enter eSS.Inactive for SW intervention
bad on the count value of cPollingTimeout.
• A downstream port shall transition to Rx.Detect upon the 360-ms timer timeout (tPollingLFPSTimeout) if cPollingTimeout is less than two and Compliance Mode is
disabled.
• A downstream port shall transition to eSS.Inactive upon the 360-ms timer timeout (tPollingLFPSTimeout) and cPollingTimeout is two.
•An upstream port of a hub shall transition to Rx.Detect upon the 360-ms timeout (tPollingLFPSTimeout) after having trained once since PowerOn Ret and the conditions to
transition to Polling.RxEQ are not met.
• A peripheral device shall transition to eSS.Disabled upon the 360-ms timeout
(tPollingLFPSTimeout) after having trained once since PowerOn Ret and the conditions to
transition to Polling.RxEQ are not met.
• A downstream port shall transition to eSS.Disabled when directed.
• A downstream port shall transition to Rx.Detect when directed to issue Warm Ret.
