It is not recommended to use such pin as input function. An “open drain pin” means it can sink at least 4mA current. It can be used as input or output function and needs an external pull up resistor. An “8051 standard pin” is a pseudo open drain pin. It can sink at least 4mA current when output is at low level, and drives at least 4mA current for 160nS when output transits from low to high, then keeps driving at 120μA to maintain the pin at high level. It can be used as input or output function. It needs an external pull up resistor when driving heavy load device. There is an internal pull-up resistance on each CMOS PAD and an internal pull-down resistance on each input PAD. It is recommended to add a pull high resistance on each open drain pin.
