Struct Frindex 

#[repr(transparent)]
pub struct Frindex(pub u32);

USB Frame Index. F70RM 44.6.1.22 (text line 114351). Raw numeric frame/microframe counter. In Host mode it updates every 125 microseconds; bits n:3 index the periodic frame list, with n selected by USBCMD frame-list size. Bits 13:3 contain the frame number and bits 2:0 the microframe. Only 32-bit writes are defined, and Host-mode writes require the Halted state (USBSTS.HCH=1, USBCMD.RS=0); writes also affect the SOF value. In Device mode the register is read-only and the received SOF updates the frame/microframe counter. The table in RM 44.6.1.22 refers to USBCMD frame-list-size encodings, not legal FRINDEX counter values.

Implementations

impl Frindex

pub const fn frindex(&self) -> u16

Frame Index. Raw numeric counter: bits 13:3 frame number, bits 2:0 microframe; not a frame-list-size selector.

pub const fn set_frindex(&mut self, val: u16)

Frame Index. Raw numeric counter: bits 13:3 frame number, bits 2:0 microframe; not a frame-list-size selector.

Trait Implementations

impl Clone for Frindex

fn clone(&self) -> Frindex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Frindex

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

Formats the value using the given formatter.

impl Default for Frindex

fn default() -> Frindex

Returns the “default value” for a type.

impl PartialEq for Frindex

fn eq(&self, other: &Frindex) -> 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.
