ADC Conversion Priority
ADC Conversion Priority
 When multiple SOC flags are set at the same
time – priority determines the order in which
they are converted
 Round Robin Priority (default)
 No SOC has an inherent higher priority than
another
 Priority depends on the round robin pointer
 High Priority
 High priority SOC will interrupt the round robin
wheel after current conversion completes and
insert itself as the next conversion
 After its conversion completes, the round robin
wheel will continue where it was interrupted
