3. In the ADCBase 0 tab of the SPIController window, find the CLOCK DIVIDE(B) box (see Figure
9), and the MODES(8) box (see Figure 10). If using the clock divider, use the drop-down box to
select the correct clock divide ratio, if necessary. If there is any interruption of the ADC clock
during power-up or during operation, a Digital Reset may be needed to re-initialize the ADC (Figure
10). For additional information, refer to the data sheet, the AN-878 Application Note, High Speed
ADC SPI Control Software, and the AN-877 Application Note, Interfacing to High Speed ADCs via SPI.
