However,by supervising their output operands, the user can dynamically enable or disable control pushbuttons for security reasons.Each control pushbutton asserts its own FlexLogic operand. Each operand need to be configured appropriately to performthe required function. Each operand remains asserted as long as the pushbutton is pressed and resets when thepushbutton is released. A dropout delay of 100 ms is incorporated to ensure fast pushbutton manipulation is recognizedby various features that can use control pushbuttons as inputs.
