<p class="hcp2">A logic NOR gate takes two or more logic-level
inputs and produces a single logic-level output. The NOR gate behaves
according to the truth table below. The output of the NOR gate will be
LOW (0) when any input is HIGH (1). The output will be HIGH (1) only when
all inputs are LOW (0).</p>
<p class="hcp2">The lights on the logic object design block
indicate the current state of the inputs and output. These are operational
in simulation and when online to the device.</p>
