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

Register hc_rh_descriptor_a writer

Implementations

impl W

pub fn no_power_swithcing(&mut self) -> NO_POWER_SWITHCING_W<'_, 8>

Bit 8 - NoPowerSwithcing

These bits are used to specify whether power switching is supported or ports are always powered. It is implementation- specific. When this bit is cleared, the PowerSwitchingMode specifies global or per-port switching.

pub fn power_switching_mode(&mut self) -> POWER_SWITCHING_MODE_W<'_, 9>

Bit 9 - PowerSwitchingMode

This bit is used to specify how the power switching of the Root Hub ports is controlled. It is implementation-specific. This field is only valid if the NoPowerSwitching field is cleared.

pub fn over_current_protection_mode( &mut self, ) -> OVER_CURRENT_PROTECTION_MODE_W<'_, 11>

Bit 11 - OverCurrentProtectionMode

This bit describes how the overcurrent status for the Root Hub ports are reported. At reset, these fields should reflect the same mode as PowerSwitchingMode. This field is valid only if the NoOverCurrentProtection field is cleared. 0 Over-current status is reported collectively for all downstream ports. 1 Over-current status is reported on per-port basis.

pub fn no_over_current_protection( &mut self, ) -> NO_OVER_CURRENT_PROTECTION_W<'_, 12>

Bit 12 - NoOverCurrentProtection

This bit describes how the overcurrent status for the Root Hub ports are reported. When this bit is cleared, the OverCurrentProtectionMode field specifies global or per-port reporting.

pub fn power_on_to_power_good_time( &mut self, ) -> POWER_ON_TO_POWER_GOOD_TIME_W<'_, 24>

Bits 24:31 - PowerOnToPowerGoodTime[POTPGT]

This byte specifies the duration HCD has to wait before accessing a powered-on port of the Root Hub. It is implementation-specific. The unit of time is 2 ms. The duration is calculated as POTPGT * 2ms.

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

Writes raw bits to the register.

Methods from Deref<Target = W<HC_RH_DESCRIPTOR_A_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
