cnfg_lower_threshold_3
Description
lower_threshold_3_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. 5F (cnfg_decay_rate_3), in
which this does not occur, the accumulator is
decremented by 1.
The lower_threshold_3_value is the value at which
the Leaky Bucket will reset an inactivity alarm.
cnfg_bucket_size_3
Description
bucket_size_3_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. 5F (cnfg_decay_rate_3), 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.
