The following program will set channel 1 of the 1st adapter to voltage input mode and channel 2 to current
input mode, and will store the converted A/D value of channel-1 data into D100 and that of channel-2 data
into D101.
Even if the input data is not stored into D100 or D101, the data registers D8260 or D8261 can be directly used
in the timer/counter setting value or in a PID instruction.
