Struct d1_pac::usb1::ehci_operational::periodiclistbase::W

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

Register periodiclistbase writer

Implementations

impl W

pub fn base_address(&mut self) -> BASE_ADDRESS_W<'_, 12>

Bits 12:31 - Base Address

These bits correspond to memory address signals [31:12], respectively.

This register contains the beginning address of the Periodic Frame List in the system memory.

System software loads this register prior to starting the schedule execution by the Host Controller. The memory structure referenced by this physical memory pointer is assumed to be 4 Kbyte aligned. The contents of this register are combined with the Frame Index Register (FRINDEX) to enable the Host Controller to step through the Periodic Frame List in sequence.

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

Writes raw bits to the register.

Methods from Deref<Target = W<PERIODICLISTBASE_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<PERIODICLISTBASE_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<PERIODICLISTBASE_SPEC>> for W

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

Converts to this type from the input type.
