The Leaky Bucket type activity monitor operates on
a 128 ms cycle. If, during a cycle, it detects that an
input has either failed or has been erratic, then for
each cycle in which this occurs, the accumulator is
incremented by 1, and for each period of 1, 2, 4, or
8 cycles, as programmed in this register, in which
this does not occur, the accumulator is
decremented by 1.
The Leaky Bucket can be programmed to "leak" or
"decay" at the same rate as the "fill" cycle, or
effectively at one half, one quarter, or one eighth of
the fill rate.
00
Bucket decay rate of 1 every 128 ms.
01
Bucket decay rate of 1 every 256 ms.
10
Bucket decay rate of 1 every 512 ms.
11
Bucket decay rate of 1 every 1024 ms.

input has either failed or has been erratic, then for
each cycle in which this occurs, the accumulator is
incremented by 1, and for each period of 1, 2, 4, or
8 cycles, as programmed in register 57h, in which
this does not occur, the accumulator is
decremented by 1.
When the accumulator count reaches the value
programmed as the upper_threshold_1_value, the
Leaky Bucket raises an input inactivity alarm.
