My customer ask me about PMIC_STBY_REQ signal between VSNVS power-up and POR_B to Hi.
It have some QA in Community but answer have 2 type.
One is a keep L signal is correct and must check power-up sequence.
Other is a undefined state so signal can not fixed to L or H.
Signal on our customer board, go to H after VSNVS on and return L before POR_B to H.
Does It have some problem on customer board and it must fixed?
or It is correct because signal state is undefined.
Which is correct answer?
