AD5754 Power-up sequence

Dear sir,

in the AD5754 datasheet it is written that if power-up sequence is not correct, the G1 and G2 transmission gates are at an undefined state, but I don't understand if this undefined state is only at power-up or if the device remain in undefined state permanently also if I set the registers in order to drive the output voltage? In my application the initial state of output is "don't care", so for me is not a problem if the undefined state is only at power-up, because next i will program the correct value for output...

Thanks in advance for you answer.

Best Regards,
