Functional description
If input En is set, then the function issues one of four possible analog values V1 to V4 at the
output A, depending on the value of S1 and S2.
If the input En is not set, then the function issues the analog value 0 at output A.
Analog output
If you interconnect this special function with a real analog output, note that the analog output
can only process values between 0 and 1000. To do this, you may need to connect an
additional amplifier between the analog output of the special function and the real analog
output. Using this amplifier, you standardize the output range of the special function to a value
range of 0 to 1000.
