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.
Reserved.
These bits set a decay rate for the internal leaky bucket accumulator:
00: The accumulator decreases by 1 in every 128 ms with no event detected.
01: The accumulator decreases by 1 in every 256 ms with no event detected. (default)
10: The accumulator decreases by 1 in every 512 ms with no event detected.
11: The accumulator decreases by 1 in every 1024 ms with no event detected.

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.
