Struct stm32h7x3::iwdg::iwdg_kr::W [] [src]

pub struct W { /* fields omitted */ }

Value to write to the register

Methods

impl W
[src]

[src]

Reset value of the register

[src]

Writes raw bits to the register

[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)
