FrameNumberOverflow. This bit is set when the MSB of
HcFmNumber (bit 15) changes value, from 0 to 1 or from 1
to 0, and after HccaFrameNumber has been updated.
RootHubStatusChange. This bit is set when the content of
HcRhStatus or the content of any of
HcRhPortStatus[NumberofDownstreamPort] has changed.
OwnershipChange. This bit is set by HC when HCD sets
the OwnershipChangeRequest field in
HcCommandStatus. This event, when unmasked, will
always generate a System Management Interrupt (SMI)
immediately. This bit is tied to 0b when the SMI pin is not
implemented.
Reserved. Unknown During Read.
SchedulingOverrun. Enable interrupt generation due to
Scheduling Overrun.
WritebackDoneHead. Enable interrupt generation due to
HcDoneHead Writeback.
StartofFrame. Enable interrupt generation due to Start of
Frame.
ResumeDetected. Enable interrupt generation due to
Resume Detect.
UnrecoverableError. Enable interrupt generation due to
Unrecoverable Error.
