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 a lower threshold for the internal leaky bucket accumulator. When the number of the accumulated
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.
