We are in the begining of a new BG95 design.
We have an external micro controller running at 1.8V -
i.e. we want to directly connect to bg95 uart interfaces (debug, main, gnss) WITHOUT the level converter used in the ref. design.
So to keep current consumption at very lowest -
the question is what are the uart gpio states for bg95 in psm - are they at a fixed level - pulled up /down or floating etc. ?
