How to achieve the "Shut down" / "power off" Power Mode

[berlese]

Hello everyone! =]

I'm trying to achieve a very low current consumption with the ESP8266 (~1uA or less).

And in the datasheet we have the follow description:


So... My question is:
How can I achieve "Power off" mode, at the bottom of the table (some times called "shut down" mode)?

That's interesting, It almost seems like if you do that, you'll need to wake it by an external rst pin reset because my bets are that the interal RTC/Ticks would not be active and the chip would be unable to reawake on its own as it does in deep sleep. If you find out more on this idea come back and post here (I will too)
