In my application I have configured IWDG to start running.
I would like to prevent the IWDG from resetting the MCU while in stop 1 mode for extended period of time.
In the reference manual it says: "Once running, the IWDG cannot be stopped."
But in the RCC section of the manual it says
"The LSI RC can be switched on and off using the LSION bit in the Control/status register (RCC_CSR)."
This would lead me to believe that its possible to turn off the LSI clock after the IWDG has been enabled.
If I try to turn off the LSI clock before entering Stop 1 mode, the MCU ends up being reset by the IWDG.
Is it true that LSI cannot be stopped ig IWDG has been engaged?
