PRODUCTION DATA
In this mode, the ADC captures the next sixteen conversion results after the ALERT pin is asserted. Once these sixteen conversions are stored in the data buffer, all conversion stops. For this mode, Set DATA_BUFFER_OPMODE to 110b. In this mode, the ADC starts converting the data on setting the SEQ_START bit and stores the data in the data buffer when one of the digital comparator flags is set after the crossing a high threshold or a low threshold for the channels selected in the sequence. if the SEQ_ABORT bit is set before the data buffer is filled, the ADC aborts the sequence and stops storing the conversion results.
Figure 7-17 and Figure 7-18 show the filling of the data buffer in autonomous mode with post-ALERT data.
