Hello. I am developing with STM32G070R8T6. It seems that there is interference between PA10 and PB15: whenever PA10 goes high, PB15 (with external pull-up) is driven at 1 V. This happens even in reset, so it is not a firmware bug. No hw connection. Tks

Thank you, Jan, it works.

I was using an old version of the DataSheet, yet even the most recent version doesn't mention PB15. The Reference manual is correct (RM0454, page 178).
