However, if SYNC is brought high before the 31st falling edge, it acts as an interrupt to the write sequence; the shift register resets and the write sequence is discarded.

One set is for the DAC channels and the other set is for the internal reference. For more information on powering down the reference, see the Enable/Disable Internal Reference section. DAC Power-Down Commands The DAC7568, DAC8168, and DAC8568 use four modes of operation.
