• 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).
