DEFAULT READBACK CONDITIONS
All pointer byte bits power up to 0. Therefore, if the user
initiates a readback without first writing to the pointer byte, no
single DAC channel has been specified. In this case, the default
readback bits are all 0 except for the CLR bit and the PD bit,
which are 1.
MULTIPLE DAC WRITE SEQUENCE
Because there are individual bits in the pointer byte for each DAC,
it is possible to write the same data and control bits to two, three,
or four DACs simultaneously by setting the relevant bits to 1.

MULTIPLE DAC READBACK SEQUENCE
If the user attempts to read back data from more than one DAC
at a time, the part reads back the power-on condition of GAIN,
BUF, and data bits (all 0), and the current state of CLR and PD .
