Dear Specialists,
My customer is considering TUSB8044A and has a question.
I would be grateful if you could advise.

The data sheet P12 has the following description.
<<<As long as GRSTz is de-asserted after both supplies are stable, there is no power-on relationship between VDD33 and VDD.
If GRSTz is only connected to a capacitor to GND, then VDD must be stable minimum of 10 µs before VDD33.>>>
Is it possible to understand that if GRSTz is H level, there is no problem even if VDD33 rises before VDD?
(The td1 in Figure 1 of the data sheet P.13 is min0, but is there any problem if it becomes negative?

I appreciate your great help in advance.
Best regards,
Shinichi
