* Stresses above those listed under "Absolute Maximum Ratings" may cause permanent
damage to the device. This a stress rating only. Functional operation of the device at
these or any other condition above those indicated in the operation sections of this
specification, is not implied. Exposure to Absolute Maximum Ratings for extended
periods may affect device reliability.
Note 1: A diode is internally connected between this pin and VDD. Provided current is
externally limited to 300µA max, no damage will occur.
