STM32G0B1CET6N VDDIO2

[ben-sachs]

Hello I'm trying to wire up the STM32G0B1CET6N and I don't know how to use the VDDIO2 pin. What is it for and how should I wire it?

For the STM32G0B1CET6N, the VDDIO2 supply powers GPIO PG[15:2]. In a normal design, you can tie VDDIO2 to VDD and add a local decoupling capacitor.

Did you check the datasheet?
