the FlexLogic operand configured under this setting is logic 1 ("On"), then the operating signal is A + B. The element
switches between adding and subtracting instantly, without additional delay.

operands (if asserted), clears self-reset targets, logs a 'blocked' event if Events are enabled, and becomes

inactive. When unblocked, the element starts operating instantly. If exposed to pickup conditions for an extended period of
time and unblocked, the element picks up and starts timing out at the moment of unblocking.
