Note: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of
this specification is not implied. Exposure to the absolute maximum rating conditions for extended periods of time may affect
reliability.
CAUTION: Negative undershoots below –0.3 volts are not allowed on any pin while in the Battery Back-up mode.
