TPSM863252: Is PG active low or active high logic, i.e. does it pull low WHILE power is good or UNTIL power is good?

Tool/software:

While I'm fairly confident that PG pulls/asserts low when power is GOOD (active low logic), it isn't explicitly stated (unless I'm just missing it) whether PG is active low or active high when power is good.

Edit: I changed my mind, it makes more sense that it's active-high logic i.e. PG high means Power is Good.

Some other parts, LMZ31704 for example, explicitly state that PWRGD asserts low when power is NOT good (active high logic).

Which is it, officially?
