void IWDG_Enable(void)
Enables IWDG (write access to IWDG_PR and IWDG_RLR registers disabled).
void IWDG_WriteAccessCmd(uint16_t IWDG_WriteAccess)
Enables or disables write access to IWDG_PR and IWDG_RLR registers.
void IWDG_SetWindowValue(uint16_t WindowValue)
Sets the IWDG window value.
void IWDG_ReloadCounter(void)
Reloads IWDG counter with value defined in the reload register (write access to IWDG_PR and IWDG_RLR ...
void IWDG_SetReload(uint16_t Reload)
Sets IWDG Reload value.
void IWDG_SetPrescaler(uint8_t IWDG_Prescaler)
Sets IWDG Prescaler value.
FlagStatus IWDG_GetFlagStatus(uint16_t IWDG_FLAG)
Checks whether the specified IWDG flag is set or not.
