Functionality
OR and OR6 are used to form general combinatory expressions with Boolean
variables.
The O output is activated when at least one input has the value TRUE. The default
value of all inputs is FALSE, which makes it possible to use only the required
number of inputs and leave the rest disconnected.
OR has two inputs and OR6 has six inputs.
