1. Min and max values are calculated according to simulation results; functionality is guaranteed by measuring a directly
correlated parameter
Note:
It is not recommended that gain control and Softstep control be adjusted at the same time if
they are in the same byte.
It is not allowed to change multistep on/off or softstep on/off during the process of multistep
or softstep.
