Do I need to connect VSSDSI when not using the display blocks?

[exlabs]

Hello,

I'm using a STM32F479VI but I do not need the DSI (display) functionality for my current application.

It seems that block runs on a independent power supply derived from VDD.

Can I leave the DSI power pins floating or should I power them anyway?

Yes, per the datasheet:

Thank you! I did read the datasheet.. but not well enough. That is exactly what I needed to know, including the part about the caps.
