Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is
not implied. Exposure to absolute maximum rating conditions for extended periods can affect device reliability.

supply is greater than the guaranteed minimum operating voltage, that reset threshold should be considered the minimum operating
point since execution ceases once the part enters the reset state. When the reset threshold for a given supply is lower than the
guaranteed minimum operating voltage, there exists a range of voltages for either supply, (V
3.0V), where the processor’s operation is not guaranteed, and the reset trip point has not been reached. This should not be an issue in
