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.
