How to Set VREFBUF to Internal Voltage Refence

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?

Hello @BenG 

I confirm that it is an issue on the STM32CubeMX. I've escalated to the concerned team for correction (under internal ticket number 192092).

 

Best Regards.

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
