pub struct Hold<'a, _T: RegTag> { /* fields omitted */ }

[−] Expand description

Floating-point context control register.

Methods

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn aspen(&self) -> bool[−]

When this bit is set to 1, execution of a floating-point instruction sets the CONTROL.FPCA bit to 1.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn set_aspen(&mut self) -> &mut Self[−]

When this bit is set to 1, execution of a floating-point instruction sets the CONTROL.FPCA bit to 1.

pub fn clear_aspen(&mut self) -> &mut Self[−]

When this bit is set to 1, execution of a floating-point instruction sets the CONTROL.FPCA bit to 1.

pub fn toggle_aspen(&mut self) -> &mut Self[−]

When this bit is set to 1, execution of a floating-point instruction sets the CONTROL.FPCA bit to 1.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn lspen(&self) -> bool[−]

Enables lazy context save of FP state.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn set_lspen(&mut self) -> &mut Self[−]

Enables lazy context save of FP state.

pub fn clear_lspen(&mut self) -> &mut Self[−]

Enables lazy context save of FP state.

pub fn toggle_lspen(&mut self) -> &mut Self[−]

Enables lazy context save of FP state.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn monrdy(&self) -> bool[−]

Indicates whether the software executing when the processor allocated the FP stack frame was able to set the DebugMonitor exception to pending.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn bfrdy(&self) -> bool[−]

Indicates whether the software executing when the processor allocated the FP stack frame was able to set the BusFault exception to pending.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn mmrdy(&self) -> bool[−]

Indicates whether the software executing when the processor allocated the FP stack frame was able to set the MemManage exception to pending.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn hfrdy(&self) -> bool[−]

Indicates whether the software executing when the processor allocated the FP stack frame was able to set the HardFault exception to pending.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn thread(&self) -> bool[−]

Indicates the processor mode when it allocated the FP stack frame.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn user(&self) -> bool[−]

Indicates the privilege level of the software executing when the processor allocated the FP stack frame.

impl<'a, _T: RegTag> Hold<'a, _T>[−]

pub fn lspact(&self) -> bool[−]

Indicates whether Lazy preservation of the FP state is active.
