Implementations

impl WatchDog<Enabled, Unlocked>

pub fn configure(self, config: WDogConfig) -> WatchDog<Enabled, Locked>

Load a configuration and start the watchdog

per KEA64RM 16.3.2 pg193-194, all registers except count must be written to for configuration to take effect. The Window register may be omited if not in windowed mode.

Note: Configuring in an unlocked state with the debugger is attached will have little useful effect.

pub fn into_disabled(self) -> WatchDog<Disabled, Locked>

Disable the WatchDog

impl WatchDog<Enabled, Locked>

pub fn into_disabled(self) -> WatchDog<Disabled, Locked>

Unlock and disable the WatchDog

impl<UpdateState> WatchDog<Enabled, UpdateState>

pub fn service(&self)

Service the Watchdog

Restart the countdown for MCU reset. This is often called petting, feeding, or kicking the watchdog.

pub fn counts(&self) -> u16

Return the current value of the watchdog’s counter

This function swaps the bytes from the big endian registers to little endian representation used.

impl<State> WatchDog<State, Locked>

pub fn configure(self, config: WDogConfig) -> WatchDog<Enabled, Locked>

Unlock, enable, and reconfigure

Note: Configuring in a locked state with the debugger attached will trigger an immediate reset.

pub fn into_sealed(self) -> WatchDog<State, Sealed>

Seals the WatchDog peripheral.

This prevents any further modifications to the watchdog, aside from servicing as needed.

impl<State, UpdateState> WatchDog<State, UpdateState>

pub fn configuration(&self) -> WDogConfig

Returns a WDogConfig containing the current state of the peripheral

pub fn interrupt_ran(&self, acknowledge: bool) -> bool

Checks if the interrupt_ran.

If acknowledge argument is true, then clear the interrupt flag if it is set.
