[−]
[src]
pub struct W { /* fields omitted */ }
Value to write to the register
Methods
impl W
[src]
fn reset_value() -> W
[src]
Reset value of the register
unsafe fn bits(&mut self, bits: u32) -> &mut Self
[src]
Writes raw bits to the register
fn key(&mut self) -> _KEYW
[src]
Bits 0:15 - Key value (write only, read 0x0000) These bits must be written by software at regular intervals with the key value 0xAAAA, otherwise the watchdog generates a reset when the counter reaches 0. Writing the key value 0x5555 to enable access to the IWDG_PR, IWDG_RLR and IWDG_WINR registers (see Section23.3.6: Register access protection) Writing the key value CCCCh starts the watchdog (except if the hardware watchdog option is selected)
