Set initial timeout value for IWDG in ms if enabled at boot. |
|
|
|
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. |
