Description
Bit Value Value Description
[7:0]
upper_threshold_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.
When the accumulator count reaches the value
programmed as the upper_threshold_0_value, the
Leaky Bucket raises an input inactivity alarm.
-
Value at which the Leaky Bucket will raise an
inactivity alarm.
