bucket_size_0_value
The Leaky Bucket 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 Reg. 53 (cnfg_decay_rate_0), in
which this does not occur, the accumulator is
decremented by 1.
The number in the Bucket cannot exceed the value
programmed into this register.
-
Value at which the Leaky Bucket will stop
incrementing, even with further inactive periods.

decay_rate_0_value
The Leaky Bucket 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.
