11.1.6 General Handling Guidelines for CMOS-Type Pins

To avoid potentially damaging current caused by floating CMOS input-only pins, TI recommends that unused input pins be tied through a pullup resistor to its associated power supply, or a pulldown to ground. For inputs with internal pullup or pulldown resistors, adding an external pullup or pulldown resistor is unnecessary unless specified in the Pin Configuration and Functions section. Note that internal pullup and pulldown resistors are weak and should not be expected to drive an external line.

After power-up or device reset, bidirectional pins are configured as inputs as a reset default until directed otherwise.

Unused output-only pins can be left open.
