LED ones:
0: Keep on integral adjustment when the
frequency achieves the upper and low
limit; the integration shows the change
between the reference and the feedback
unless it reaches the internal integral
limit. When the trend between the
reference and the feedback changes, it
needs more time to offset the impact of
continuous working and the integration
will change with the trend.
1: Stop integral adjustment when the
frequency achieves the upper and low
limit. If the integration keeps stable, and
