Yes there are max and min for each parameter (not necessarily 0%/100%)
As an example if we take squelch detector threshold, the register value
vs actual percentage changer as per data book is as follows :
% change in voltage | corresponding reg value
-20.90% | 7
-15.60% | 6
-10.30% | 5
-5.30% | 4
0% | 3
5.30% | 2
10.60% | 1
15.90% | 0
Here the min and max are 15.9% to -20.9%
The min and max differ for each parameter and might not be necessarily
0% and 100%
them ("minimum: xxxx").
Best regards,
Krzysztof
