Struct d1_pac::usb1::ehci_operational::frindex::W

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

Register frindex writer

Implementations

impl W

pub fn frame_index(&mut self) -> FRAME_INDEX_W<'_, 0>

Bits 0:13 - Frame Index

The value in this register increment at the end of each time frame (e.g. micro-frame). Bits[N:3] are used for the Frame List current index. It means that each location of the frame list is accessed 8 times (frames or Micro-frames) before moving to the next index. The following illustrates values of N based on the value of the Frame List Size field in the USBCMD register.

pub unsafe fn bits(&mut self, bits: u32) -> &mut Self

Writes raw bits to the register.

Methods from Deref<Target = W<FRINDEX_SPEC>>

pub unsafe fn bits(&mut self, bits: REG::Ux) -> &mut Self

Writes raw bits to the register.

Safety

Read datasheet or reference manual to find what values are allowed to pass.

Trait Implementations

impl Deref for W

type Target = W<FRINDEX_SPEC>

The resulting type after dereferencing.

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

Dereferences the value.

impl DerefMut for W

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl From<W<FRINDEX_SPEC>> for W

fn from(writer: W<FRINDEX_SPEC>) -> Self

Converts to this type from the input type.
