3. These pins are provided with a latch. Therefore, when they go into a high-impedance state, they hold
the status before the high-impedance state until driven by an external device. It is not necessary to pull
up or down the data bus. To invert the level of the pin that goes into a high-impedance state by an
external device, a drive current higher than the latch invert current (IILH, IILL) is necessary.
