Bit SCUEN of PWR peripheral of STM32H7

[Gpeti]

We don't understand the bit SCUEN of STM32H7.

 

The description is not very clear:

 

 

 

Could you explain what SCUEN means and if the software is supposed to write or read this bit and why ?

Where have you seen this? I tried to find in my STM32H7 manuals but I do not see anything for SCUEN.

Where is coming from? (provide doc name, link and page as info, thank you).

It's in the technical reference manual, nothing exotic...

Chapter 6 "PWR"

No SCUEN bit in RM0468 for STM32H723/733, STM32H725/735 and STM32H730

Okay, RM0433.

You should always say which STM32 / H7 exactly you are using, even in the "basic" registers there seem to be some differences between the H7 types.

I would check how the HAL libraries are using this bit, if they are using it all.
