4.14 DEVICE_REG (0x0D)
This register provides 4 separate bytes for controlling the initialisation sequence and the DLL setting
( clock-frequency dependent) used in the DAC automatic initialisation sequence.
The top 16 bits (1 byte for each channel) are used to specify the DLL setting forced into the DAC serial
initialisation stream to handle differences between different DACs.
The bottom 16 bits (1 byte for each channel) allow dynamic selection of the (device specific) DAC initialisation
sequence if required.

sequence triggered by strobe bit).
