The designation typically refers to how the counting mechanism is triggered or enabled in digital circuits. "Active-high" means the function is enabled or triggered when the input is at a high voltage level, and "active-low" means it is enabled or triggered when the input is at a low voltage level. Therefore, if the up count is active-high and the down count is active-low, it means the up count is triggered by a high signal, and the down count is triggered by a low signal.
