Implementations

impl Ewcr

pub const fn ewit(&self) -> u16

Watchdog counter window value These bits are write access protected (see ). They are written by software to define at which position of the IWDCNT down-counter the early wakeup interrupt must be generated. The early interrupt is generated when the IWDCNT is lower or equal to EWIT[11:0]

• 1. EWIT[11:0] must be bigger than 1. An interrupt is generated only if EWIE = 1. The EWU bit in the must be reset to be able to change the reload value. Note: Reading this register returns the Early wakeup comparator value and the Interrupt enable bit from the VDD voltage domain. This value may not be up to date/valid if a write operation to this register is ongoing, hence the value read from this register is valid only when the EWU bit in the is reset.

pub fn set_ewit(&mut self, val: u16)

Watchdog counter window value These bits are write access protected (see ). They are written by software to define at which position of the IWDCNT down-counter the early wakeup interrupt must be generated. The early interrupt is generated when the IWDCNT is lower or equal to EWIT[11:0]

This value may not be up to date/valid if a write operation to this register is ongoing, hence the value read from this register is valid only when the EWU bit in the is reset.

pub const fn ewic(&self) -> bool

Watchdog early interrupt acknowledge The software must write a 1 into this bit in order to acknowledge the early wakeup interrupt and to clear the EWIF flag. Writing 0 has not effect, reading this flag returns a 0.

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

Watchdog early interrupt acknowledge The software must write a 1 into this bit in order to acknowledge the early wakeup interrupt and to clear the EWIF flag. Writing 0 has not effect, reading this flag returns a 0.

pub const fn ewie(&self) -> bool

Watchdog early interrupt enable Set and reset by software. The EWU bit in the must be reset to be able to change the value of this bit.

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

Watchdog early interrupt enable Set and reset by software. The EWU bit in the must be reset to be able to change the value of this bit.

Trait Implementations

impl Clone for Ewcr

fn clone(&self) -> Ewcr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Ewcr

fn default() -> Ewcr

Returns the “default value” for a type.

impl PartialEq for Ewcr

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

This method tests for self and other values to be equal, and is used by ==.

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

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