1. This parameter is guaranteed by characterization, but not tested in production.
1. Applies only to an external clock source, not when a crystal is connected to the X1 and X2 pins.
2. Tested at V
3. These parameters are characterized but not tested.
4. +/– 2.5% accuracy enables serial communication over the UART with the internal Oscillator.
5. Min frequency at hot temperature.
