P32.02 - P32.05 and P32.08 - P32.11 respectively set the upper limit, lower limit, filtering time and
limiting of the two analog input ports.
The upper limit/lower limit combination is a proportionality coefficient.
By modifying the filtering time, the anti-interference ability of the terminal input can be improved,
because the analog input through the A0 and A1 terminals in the field application usually carries a
certain interference signal. However, the longer the filtering time, the longer the response delay of
the terminal action.
