16.3.5. How to read and write parameter settings
Parameter registers are similar to the registers described above, but here you can change the settings
via interface. Mind the ranges and the percentage-flag – if a variable is expressed as percentage of a
range, a new value must also be expressed that way. Besides the percentage calculation, the range
indicates what values are possible for a variable. Since the ranges can change according to settings or
selections, the range has to be read prior to writing, to get the range, the percentage-flag setting, and
the number of decimal places.
