50 µA (typical) internal pull-up. Unless otherwise noted in the pin description, internal pull-

ups are always enabled.

Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on internal

resistors to drive signals external to the device. When connected to a load that must be

pulled high, an external resistor must be added.

50 µA (typical) internal pull-down. Unless otherwise noted in the pin description, internal

pull-downs are always enabled.

Internal pull-down resistors prevent unconnected inputs from floating. Do not rely on internal

resistors to drive signals external to the device. When connected to a load that must be

pulled low, an external resistor must be added.
