Struct Cntkctl 

pub struct Cntkctl { /* private fields */ }

CNTKCTL (Counter-timer Kernel Control Register)

Implementations

impl Cntkctl

pub const ZERO: Self

Creates a new instance with a raw value of 0. Equivalent to [Self::new_with_raw_value(0)].

pub const fn raw_value(&self) -> u32

Returns the underlying raw value of this bitfield

pub const fn new_with_raw_value(value: u32) -> Cntkctl

Creates a new instance of this bitfield with the given raw value.

No checks are performed on the value, so it is possible to set bits that don’t have any accessors specified.

pub const fn builder() -> PartialCntkctl<false, false, false, false, false, false, false>

Creates a builder for this bitfield which ensures that all writable fields are initialized.

pub const fn el0pten(&self) -> bool

Controls whether the physical timer registers are accessible from EL0 modes.

pub const fn with_el0pten(&self, field_value: bool) -> Self

Controls whether the physical timer registers are accessible from EL0 modes.

pub fn set_el0pten(&mut self, field_value: bool)

Controls whether the physical timer registers are accessible from EL0 modes.

pub const fn el0vten(&self) -> bool

Controls whether the virtual timer registers are accessible from EL0 modes.

pub const fn with_el0vten(&self, field_value: bool) -> Self

Controls whether the virtual timer registers are accessible from EL0 modes.

pub fn set_el0vten(&mut self, field_value: bool)

Controls whether the virtual timer registers are accessible from EL0 modes.

pub const fn evnti(&self) -> u4

Selects which bit of CNTVCT is the trigger for the event stream generated from the virtual counter, when that stream is enabled.

pub const fn with_evnti(&self, field_value: u4) -> Self

Selects which bit of CNTVCT is the trigger for the event stream generated from the virtual counter, when that stream is enabled.

pub fn set_evnti(&mut self, field_value: u4)

Selects which bit of CNTVCT is the trigger for the event stream generated from the virtual counter, when that stream is enabled.

pub const fn evntdir(&self) -> bool

Controls which transition of the CNTVCT trigger bit, defined by EVNTI, generates an event, when the event stream is enabled.

• true: a 1-0 transition
• false: a 0-1 transition

pub const fn with_evntdir(&self, field_value: bool) -> Self

Controls which transition of the CNTVCT trigger bit, defined by EVNTI, generates an event, when the event stream is enabled.

• true: a 1-0 transition
• false: a 0-1 transition

pub fn set_evntdir(&mut self, field_value: bool)

Controls which transition of the CNTVCT trigger bit, defined by EVNTI, generates an event, when the event stream is enabled.

• true: a 1-0 transition
• false: a 0-1 transition

pub const fn evnten(&self) -> bool

Enables the generation of an event stream from the virtual counter.

pub const fn with_evnten(&self, field_value: bool) -> Self

Enables the generation of an event stream from the virtual counter.

pub fn set_evnten(&mut self, field_value: bool)

Enables the generation of an event stream from the virtual counter.

pub const fn el0vcten(&self) -> bool

Controls whether the virtual counter, CNTVCT, and the frequency register CNTFRQ, are accessible from EL0 modes.

pub const fn with_el0vcten(&self, field_value: bool) -> Self

Controls whether the virtual counter, CNTVCT, and the frequency register CNTFRQ, are accessible from EL0 modes.

pub fn set_el0vcten(&mut self, field_value: bool)

Controls whether the virtual counter, CNTVCT, and the frequency register CNTFRQ, are accessible from EL0 modes.

pub const fn el0pcten(&self) -> bool

Controls whether the physical counter, CNTPCT, and the frequency register CNTFRQ, are accessible from EL0 modes.

pub const fn with_el0pcten(&self, field_value: bool) -> Self

Controls whether the physical counter, CNTPCT, and the frequency register CNTFRQ, are accessible from EL0 modes.

pub fn set_el0pcten(&mut self, field_value: bool)

Controls whether the physical counter, CNTPCT, and the frequency register CNTFRQ, are accessible from EL0 modes.
