Basic functions list - GF 

Basic functions represent simple logical elements of Boolean algebra. 
You can invert the inputs of individual basic functions, that is, the circuit program inverts a 

logical "1" at a relevant input to a logical "0"; if "0" is set at the input, the program sets a 

logical "1". See the programming example at Circuit program input (Page 86). 
The GF list contains the basic function blocks you can use for your circuit program. The 

following basic functions are available:
