Clock stops or if Link Resets are generated before the Unsolicited Response for the state change has

been returned to the host.

•

Reporting of ClkStopOk when stopping of the clock would be permitted. The CLKSTOP is a static ca-

pability with ClkStopOk a dynamic reporting. The setting the capability CLKSTOP to one (1) and not al-

lowing the clock to stop by not reporting ClkStopOk is not permissible. Unless there is a condition or

dependency that the host software cannot be made aware of, that would prohibit stopping the clock, the

ClkStopOk shall be reported as set (1). It is expected that host software will poll the ClkStopOk before

stopping the clock if the CLKSTOP is reported at one (1).
