7-14 Using The Sequence of Events Module in FIFO Mode
Producing Current Event Data
Figure 7.2 shows an example of the Sequence of Events module
producing the current data for the controller to retrieve it.
In the example, the Sequence of Events module produces data from
the current event for the controller.

IMPORTANT
Remember, the current event is data that the
module is currently producing from its on-board
buffer at each RPI. For more information on how the
Sequence of Events module produces data from its
on-board buffer, see page 7-2.
