4.2 Basic functions list - GF
Basic functions represent simple logical elements of Bool-
ean algebra.
You can invert the inputs of individual basic functions, i.e. 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:
