Enum SOFR

pub enum SOFR {
    NotStartOfFrame = 0,
    StartOfFrame = 1,
}

Start of frame This bit signals the beginning of a new USB frame and it is set when a SOF packet arrives through the USB bus. The interrupt service routine may monitor the SOF events to have a 1ms synchronization event to the USB host and to safely read the USB_FNR register which is updated at the SOF packet reception (this could be useful for isochronous applications). This bit is read/write but only 0 can be written and writing 1 has no effect.

Value on reset: 0

Variants

NotStartOfFrame = 0

0: NotStartOfFrame

StartOfFrame = 1

1: A SOF packet arrived through the USB bus

Trait Implementations

impl Clone for SOFR

fn clone(&self) -> SOFR

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SOFR

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Format for SOFR

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl From<SOFR> for bool

fn from(variant: SOFR) -> Self

Converts to this type from the input type.

impl PartialEq for SOFR

fn eq(&self, other: &SOFR) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
