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 21 how Data0 was thrown out to make room for
Data10.
