Struct d1_pac::usb1::ehci_capability::hcsparams::R

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

Register hcsparams reader

Implementations

impl R

pub fn n_ports(&self) -> N_PORTS_R

Bits 0:3 - This field specifies the number of physical downstream ports implemented on this host controller. The value of this field determines how many port registers are addressable in the Operational Register Space. Valid values are in the range of 0x1 to 0x0f.

pub fn port_routing_rules(&self) -> PORT_ROUTING_RULES_R

Bit 7 - This field indicates the method used by this implementation for how all ports are mapped to companion controllers.

pub fn n_pcc(&self) -> N_PCC_R

Bits 8:11 - Number of Port per Companion Controller (N_PCC)

This field indicates the number of ports supported per companion host controller host controller. It is used to indicate the port routing configuration to system software.

pub fn n_cc(&self) -> N_CC_R

Bits 12:15 - Number of Companion Controller (N_CC)

This field indicates the number of companion controllers associated with this USB2.0 host controller. A zero in this field indicates there are no companion host controllers. And a value larger than zero in this field indicates there are companion USB1.1 host controller(s).

pub fn debug_port_number(&self) -> DEBUG_PORT_NUMBER_R

Bits 20:23 - This register identifies which of the host controller ports is the debug port. The value is the port number (one based) of the debug port.

Methods from Deref<Target = R<HCSPARAMS_SPEC>>

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

Reads raw bits from register.

Trait Implementations

impl Deref for R

type Target = R<HCSPARAMS_SPEC>

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

Dereferences the value.

impl From<R<HCSPARAMS_SPEC>> for R

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

Converts to this type from the input type.
