    keyword=ARS firmware version E09

    We tested firmware E09 during run 7623. We observed the following:

    - We still get empty FIFO events sometimes, but that can also be related to our trigger logic.

    - Sync words in the event buffer are stable, except for the first board read in each of the two crates. For these boards, we notice that the first few sync words have sometimes some random values during the run.

    See attached plots for more details.
