4.2 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". A programming example is found in Chapter
3.6.3.
The GF list contains the basic function blocks you can use
for your circuit program. The following basic functions are
available:
