Hi,
I am using STM32WB55 device in my design and have to provide 3.3V from outside to BOOT0 pin BEFORE MCU is powered ON. In the datasheets and the manuals that I have been reviewing I didn't find any straightforward information what voltage level can be provided to this pin before device is powered-up.
Please let me know if someone have encountered with this topic before.
Thanks!
