Additionally to these possibilities, we can use programmable inputs for creating logic schemes using logic
AND/OR/NOT gates with the inputs, and assigning them to outputs. For creating these schemes, we must program
inputs as “Void input”.
The following lines detail the operation of each input:
•
Selection table 1 : This input is activated by level, and it’s used for switching the active settings table. Please
refer to section 2.5 for further details.
