through a pull-up or pull-down resistor (typical: 10 k for I/Os). Unused I/O pins must be tied in the same way to V

Absolute maximum ratings
Stresses above those listed as “absolute maximum ratings” may cause permanent damage
to the device. This is a stress rating only and functional operation of the device under these
conditions is not implied. Exposure to maximum rating conditions for extended periods may
affect device reliability.
