9.5 Input and output signal connections of function
blocks
9.5.1 Function block input connections
Possible sources for function block inputs are all input elements listed in the input
selection tree of the logic editor as well as the outputs of function blocks.
9.5.2 Inversion of input connections
The input connections of some function blocks can be configured as inverted. This
means that the function block evaluates a High signal at an inverted input as Low and
vice versa.
In order to invert an input, double click on the function block icon and check the
desired input on the parameter page of the function block properties dialog:
Inverted inputs are displayed with a small white circle:
Examples of function blocks with invertable inputs include the following function
blocks:
 AND
 OR
 Routing N:N
 RS Flip-Flop
 JK Flip-Flop
 Switch synchronization
