Figure 27 shows the timing of continuous conversion mode when three analog input channels are selected. The maximum
throughput rate per channel is 2 MSPS in this mode. The data flow in the bottom of the figure shows in which order the
converted data is written into the FIFO. The timing of the DATA_AV signal shown here is for a trigger level set to 3.

Figure 28 shows the timing of continuous conversion mode when four analog input channels are selected. The maximum
throughput rate per channel is 1.5 MSPS in this mode. The data flow in the bottom of the figure shows in which order the
converted data is written into the FIFO. The timing of the DATA_AV signal shown here is for a trigger level of 4.
