Two MSBs represent a power-down condition and 16
LSBs represent data for TR and DR. By adding bits
17 and 18 to TR and DR, a power-down condition
can be temporarily stored and used as data. Internal
circuits ensure that DB15 and DB14 get transferred
to TR17 and TR16 (DR17 and DR16), when DB16 =
1.
The DAC8554 treats the power-down condition as
