DAC Control
As mentioned in the heading of this section, the details of all of the functions and bits are
described in detail in the NAU8822 Design Guide and appendices. The bit names match this
documentation, and using a text string search in the Design Guide is a good method to quickly
locate specific information about a specific control bit function.

Oversampling
DAC and ADC performance is optimized when both are operated at the same oversampling rate.
An added feature of the GUI Application is that when either the ADC or DAC oversampling rate is
changed, both are changed by the application. If it is desired to make the ADC and DAC operate
at different oversampling rates, this can be done using the Register Map control tab.
