EVAL-AD7719-EB
The Main ADC Control Register Screen
Fig. 8. shows the Main ADC Control Register Screen. This register controls the Word-length, Bipolar/Unipolar
operation, Channel selection and Range selection for the Main ADC. When the screen is loaded the software reads
the current contents from the Main ADC Control Register of the AD7719 and sets the buttons accordingly. Note
if the Channel Configure bit is set in the Mode Register the channels the Main and Aux ADCs can use is changed - see
AD7719 datasheets for more information. Everytime a change is made, the software writes the new conditions to the
AD7719 and then reads back from the Main ADC Control Register for conformation. The Aux ADC Control Register
Screen performs a similar operation for the Aux ADC Control Register - see AD7719 datasheets for more information.
