pub fn wdh(&self) -> WDH_R

Bit 1 - WritebackDoneHead This bit is set immediately after HC has written HcDoneHead to HccaDoneHead.

pub fn sf(&self) -> SF_R

Bit 2 - StartofFrame This bit is set by HC at each start of a frame and after the update of HccaFrameNumber.

pub fn ue(&self) -> UE_R

Bit 4 - UnrecoverableError This bit is set when HC detects a system error not related to USB.

pub fn fno(&self) -> FNO_R

Bit 5 - 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.

pub fn rhsc(&self) -> RHSC_R

Bit 6 - RootHubStatusChange This bit is set when the content of HcRhStatus or the content of any of HcRhPortStatus[NumberofDownstreamPort] has changed.
