When the power up indicator pin, PUI, is set LOW all internal circuits will go into the power down state.
It will take 2 to 10 milliseconds for the PLL to lock when operation is resumed with the FST and BCLK
signals applied and PUI set HIGH. An additional 1-millisecond delay is used to set the analog outputs
to the signal ground reference in order to avoid power up glitches. The digital open drain outputs will
remain at high impedance during this power up delay.
The following table shows the states of the output pins in the power save or power down mode.
