Functional description 
If input En is set, then the function issues one of four possible analog values V1 to V4 at the 
output AQ, 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 AQ. 
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.
