Implementations

impl DivCsr

pub const fn ready(&self) -> bool

Reads as 0 when a calculation is in progress, 1 otherwise. Writing an operand (xDIVIDEND, xDIVISOR) will immediately start a new calculation, no matter if one is already in progress. Writing to a result register will immediately terminate any in-progress calculation and set the READY and DIRTY flags.

pub fn set_ready(&mut self, val: bool)

Reads as 0 when a calculation is in progress, 1 otherwise. Writing an operand (xDIVIDEND, xDIVISOR) will immediately start a new calculation, no matter if one is already in progress. Writing to a result register will immediately terminate any in-progress calculation and set the READY and DIRTY flags.

pub const fn dirty(&self) -> bool

Changes to 1 when any register is written, and back to 0 when QUOTIENT is read. Software can use this flag to make save/restore more efficient (skip if not DIRTY). If the flag is used in this way, it’s recommended to either read QUOTIENT only, or REMAINDER and then QUOTIENT, to prevent data loss on context switch.

pub fn set_dirty(&mut self, val: bool)

Changes to 1 when any register is written, and back to 0 when QUOTIENT is read. Software can use this flag to make save/restore more efficient (skip if not DIRTY). If the flag is used in this way, it’s recommended to either read QUOTIENT only, or REMAINDER and then QUOTIENT, to prevent data loss on context switch.

Trait Implementations

impl Clone for DivCsr

fn clone(&self) -> DivCsr

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for DivCsr

fn default() -> DivCsr

Returns the “default value” for a type.

impl PartialEq for DivCsr

fn eq(&self, other: &DivCsr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
