ADC0 Operation
Step 1. Choose the start of conversion source.
Step 2. Choose Normal Mode or Burst Mode operation.
Step 3. If Burst Mode, choose the ADC0 Idle Power State and set the Power-Up Time.
Step 4. Choose the tracking mode. Note that Pre-Tracking Mode can only be used with Normal
Step 5. Calculate required settling time and set the post convert-start tracking time using the
Step 6. Choose the repeat count.
Step 7. Choose the output word justification (Right-Justified or Left-Justified).
Step 8. Enable or disable the End of Conversion and Window Comparator Interrupts.
