IWDG with LSI on STM32L0

Hi all,

I´m trying to implement a Independent Watchdog functionality on my STM32L0.

In HAL description pdf I´ve read the following sentence that give me some doubts on me:

STM32L0xx devices provide the capability to measure the
LSI frequency (LSI clock connected internally to TIM5 CH4 input capture). The measured
value can be used to have an IWDG timeout with an acceptable accuracy.

1.- Has anyone the code example to do that?

2.- Can I use the LSI clock only to IWDG while I am using the HSE with my application?

Best regards
