Sequence Complete Flag — This flag is set upon completion of a conversion sequence. If conversion
sequences are continuously performed (SCAN = 1), the flag is set after each one is completed. This flag is
cleared when one of the following occurs:
0 Conversion sequence not completed
1 Conversion sequence has completed
External Trigger Overrun Flag — While in edge trigger mode (ETRIGLE = 0), if additional active edges are
detected while a conversion sequence is in process the overrun flag is set. This flag is cleared when one of the
following occurs:
0 No External trigger over run error has occurred
1 External trigger over run error has occurred
