Note
If the load voltage (L+) is switched off and on, this may result in incorrect output
values at the output for approx. 10 ms.
Parameter
You will find a description of the general procedure for assigning parameters to
analog modules in Section 4.7.
You will find an overview of the programmable parameters and their default values
in Table 4-42, on page 4-43.
