In FIFO, Stream, FILO, and Trigger (after a trigger event has occurred) modes, the
buffer continues filling sequentially after the Sample Threshold is reached. Sample
accumulation after the buffer is full depends on the selected operation mode. FIFO and
Trigger modes stop accumulating samples when the buffer is full, and Stream and FILO
modes begin discarding the oldest data when new samples are accumulated.

After the buffer has been filled in FILO or Stream mode, the oldest samples are
discarded when new samples are collected. Note in Figure 16 how Data0 was thrown out to
make room for Data10.
