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 sensitive 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 overrun error has occurred
1 External trigger overrun error has occurred
Result Register Overrun Flag — This bit indicates that a result register has been written to before its associated
conversion complete flag (CCF) has been cleared. This flag is most useful when using the FIFO mode because
the flag potentially indicates that result registers are out of sync with the input channels. However, it is also
practical for non-FIFO modes, and indicates that a result register has been overwritten before it has been read
(i.e. the old data has been lost). This flag is cleared when one of the following occurs:
0 No overrun has occurred
1 Overrun condition exists (result register has been written while associated CCFx flag was still set)
