NOTES:
1. Applies only to an external clock source, not when a crystal is connected to the X1 and X2 pins.
2. Tested at VDD = 5.0 V and room temperature.
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.
