These bits set a bucket size for the internal leaky bucket accumulator. If the number of the accumulated events reach
the bucket size, the accumulator will stop increasing even if further events are detected.

These bits set a lower threshold for the internal leaky bucket accumulator. When the number of the accumu-
lated events is below this threshold, the no-activity alarm is cleared.
These bits set an upper threshold for the internal leaky bucket accumulator. When the number of the accumu-
lated events is above this threshold, a no-activity alarm is raised.
