Description
The FLL can be switched off for debugging purposes.
In Functional mode, FLL_ON must be logic 1 for all
cases.
The default value is logic 0 to have a normal action
FLL. However, some flexibility has been included for
field investigations and debugging purposes.
With these settings, the FLL action can be reduced. For
better acquisition behavior, a large value should be
chosen. The settings are ‘don’t care’ if LIM_ON is
logic 0.
FLL off (only for debugging)
