We are using PIN PD1 and PD0 as a GPIO input. These 2 inputs are configured to pull down.
From our measurement, we found PD1 is always pulled up to 3.3v, while PD0 is always pulled down to ground. (PD3, PD2 are alright.)
We checked Errata and datasheet and we cannot have any clue.
Can you give us any idea?
Thanks a lot.
