NOTES: A. FC has to be set high for a secondary communication request when 16-bit DAC data format is used (see Section 3.2).
B. D0 = 1 means secondary communication request (software secondary request control, see Section 3.2)
C. The number of SCLKs between FS (Primary) and FS (Secondary) is 128 if cascading devices are less than 5, or 256 if cascading
devices are greater than 4.
D. The number of SCLKs per data sampling period is 256 if cascading devices are less than 5, or 512 if cascading devices are greater
than 4.
