Struct rp2040_pac::WATCHDOG

pub struct WATCHDOG { /* private fields */ }

WATCHDOG

Implementations

impl WATCHDOG

pub const PTR: *const RegisterBlock = {0x40058000 as *const watchdog::RegisterBlock}

Pointer to the register block

pub const fn ptr() -> *const RegisterBlock

Return the pointer to the register block

pub unsafe fn steal() -> Self

Steal an instance of this peripheral

Safety

Ensure that the new instance of the peripheral cannot be used in a way that may race with any existing instances, for example by only accessing read-only or write-only registers, or by consuming the original peripheral and using critical sections to coordinate access between multiple new instances.

Additionally, other software such as HALs may rely on only one peripheral instance existing to ensure memory safety; ensure no stolen instances are passed to such software.

Methods from Deref<Target = RegisterBlock>

pub fn ctrl(&self) -> &CTRL

0x00 - Watchdog control
The rst_wdsel register determines which subsystems are reset when the watchdog is triggered.
The watchdog can be triggered in software.

pub fn load(&self) -> &LOAD

0x04 - Load the watchdog timer. The maximum setting is 0xffffff which corresponds to 0xffffff / 2 ticks before triggering a watchdog reset (see errata RP2040-E1).

pub fn reason(&self) -> &REASON

0x08 - Logs the reason for the last reset. Both bits are zero for the case of a hardware reset.

pub fn scratch0(&self) -> &SCRATCH0

0x0c - Scratch register. Information persists through soft reset of the chip.

pub fn scratch1(&self) -> &SCRATCH1

0x10 - Scratch register. Information persists through soft reset of the chip.

pub fn scratch2(&self) -> &SCRATCH2

0x14 - Scratch register. Information persists through soft reset of the chip.

pub fn scratch3(&self) -> &SCRATCH3

0x18 - Scratch register. Information persists through soft reset of the chip.

pub fn scratch4(&self) -> &SCRATCH4

0x1c - Scratch register. Information persists through soft reset of the chip.

pub fn scratch5(&self) -> &SCRATCH5

0x20 - Scratch register. Information persists through soft reset of the chip.

pub fn scratch6(&self) -> &SCRATCH6

0x24 - Scratch register. Information persists through soft reset of the chip.

pub fn scratch7(&self) -> &SCRATCH7

0x28 - Scratch register. Information persists through soft reset of the chip.

pub fn tick(&self) -> &TICK

0x2c - Controls the tick generator
