Higher values indicate that the watchdog will need to be reloaded more frequently. Allowed values: 4, 8, 16, 32, 64, 128, 256. This setting combined with reload counter defines the watchdog countdown time. config IWDG_STM32_RELOAD_COUNTER int "Value for IWDG counter" depends on IWDG_STM32 default 2048 range 0 4095 help Configure the value to be loaded into the watchdog's counter each time a reload operation is performed. This value combined with prescaler setting defines the watchdog countdown time. config IWDG_STM32_START_AT_BOOT bool "Start IWDG during boot" depends on IWDG_STM32 default n help Enable this setting to allow IWDG to be automatically started during device initialization. Note that once IWDG is started it must be reloaded before the counter reaches 0, otherwise the MCU will be reset. config IWDG_STM32_DEVICE_NAME string "Device name for Independent Watchdog (IWDG)" depends on IWDG_STM32 default "IWDG" help Set the name used by IWDG device during registration. endif # SOC_FAMILY_STM32
