The min timeout supported is 1 ms. The max timeout depends on the MCU's LSI clock frequency and can be calculated with: max. prescaler value (256) * max. reload ticks (4096) / LSI freq. Limiting maximum timeout to a safe value of 26214 ms here, which was calculated for highest LSI frequency among STM32 MCUs of 40 kHz. config WWDG_STM32 bool "System Window Watchdog (WWDG) Driver for STM32 family of MCUs" default y depends on DT_HAS_ST_STM32_WINDOW_WATCHDOG_ENABLED help Enable WWDG driver for STM32 line of MCUs
