pub struct R(/* private fields */);

Register hc_interrupt_status reader

Implementations

impl R

pub fn scheduling_overrun(&self) -> SCHEDULING_OVERRUN_R

Bit 0 - SchedulingOverrun

This bit is set when the USB schedule for the current Frame overruns and after the update of. A scheduling overrun will also cause the SchedulingOverrunCount of to be incremented.

pub fn writeback_done_head(&self) -> WRITEBACK_DONE_HEAD_R

Bit 1 - WritebackDoneHead

This bit is set immediately after HC has written to. Further updates of the will not occur until this bit has been cleared. HCD should only clear this bit after it has saved the content of HccaDoneHead.

pub fn start_of_frame(&self) -> START_OF_FRAME_R

Bit 2 - StartofFrame

This bit is set by HC at each start of frame and after the update of HccaFrameNumber. HC also generates a SOF token at the same time.

pub fn resume_detected(&self) -> RESUME_DETECTED_R

Bit 3 - ResumeDetected

This bit is set when HC detects that a device on the USB is asserting resume signaling. It is the transition from no resume signaling to resume signaling causing this bit to be set. This bit is not set when HCD sets the USBRseume state.

pub fn unrecoverable_error(&self) -> UNRECOVERABLE_ERROR_R

Bit 4 - UnrecoverableError

This bit is set when HC detects a system error not related to USB. HC should not proceed with any processing nor signaling before the system error has been corrected. HCD clears this bit after HC has been reset.

pub fn frame_number_overflow(&self) -> FRAME_NUMBER_OVERFLOW_R

Bit 5 - FrameNumberOverflow

This bit is set when the MSb of (bit 15) changes value, from 0 to 1 or from 1 to 0, and after has been updated.

pub fn root_hub_status_change(&self) -> ROOT_HUB_STATUS_CHANGE_R

Bit 6 - RootHubStatusChange

This bit is set when the content of or the content of any of [ NumberofDownstreamPort ] has changed.

Methods from Deref<Target = R<HC_INTERRUPT_STATUS_SPEC>>

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<R<HC_INTERRUPT_STATUS_SPEC>> for R

fn from(reader: R<HC_INTERRUPT_STATUS_SPEC>) -> Self
