Here VCC_3V3_IN always comes first.
Then VCC_3V3_IO and VCC_1V8_IO in any order.

Could please confirm RESET will always be pulled low.

Even when VDD is raising.

Hi Felix

The RESET should go low when VDD is more than POR voltage.

Let's say VCC_3V3_IO has crossed thershold then RESET will be completely dependedent on VCC_1V8 after the delay time.

You can share the timing diagram if you want more clarification.
