Struct d1_pac::usb1::ohci_memory_pointer_partition::hc_control_head_ed::R

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

Register hc_control_head_ed reader

Implementations

impl R

pub fn ehcd_3_0(&self) -> EHCD_3_0_R

Bits 0:3 - Because the general TD length is 16 bytes, the memory structure for the TD must be aligned to a 16-byte boundary. So the lower bits in the PCED, through bit 0 to bit 3 must be zero in this field.

pub fn ehcd_31_4(&self) -> EHCD_31_4_R

Bits 4:31 - The HcControlHeadED register contains the physical address of the first Endpoint Descriptor of the Control list. HC traverse the Control list starting with the HcControlHeadED pointer. The content is loaded from HCCA during the initialization of HC.

Methods from Deref<Target = R<HC_CONTROL_HEAD_ED_SPEC>>

pub fn bits(&self) -> REG::Ux

Reads raw bits from register.

Trait Implementations

impl Deref for R

type Target = R<HC_CONTROL_HEAD_ED_SPEC>

The resulting type after dereferencing.

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

Dereferences the value.

impl From<R<HC_CONTROL_HEAD_ED_SPEC>> for R

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

Converts to this type from the input type.
