The Load Input and Output (From Shift) tab, shown in

Figure 4, allows the user to load the input and output

registers of the corresponding DAC with the data that is

sent to the shift register. The user can load all four DACs

individually or all at once by pressing the appropriate

button. If the AutoRead All Registers checkbox is

checked (see Figure 1), the new input and output regis-

ter values are updated to the software’s main window.
