I'm using at STM32H563VITz in LQFP100 package.

According to the reference manual (RM0481 Rev 21209) I can use the internal Voltage Reference (and then set it to 2.0478V)

I've also referenced the post at: How to configure VREFBUF on my STM32 - STMicroelectronics Community

When I open the .ioc file for my project. I don't have the option to select the Internal Voltage Reference

It could be a bug in Cube MX - but I suspect it's more likely that I haven't enabled some component or peripharl in the .ico file?

Thanks

Is there an estimate on how long a fix will take? (I appreciate that's like asking how long a piece of string is?)

I'll try and temporarily hack the (auto)generated code to enable it, but any advice/tips would be helpful
