Notes:
1. Resonator characteristics given by the crystal/ceramic resonator manufacturer.
2. t_SU(OSC) is the typical oscillator start-up time measured between V_DD=2.8V and the fetch of the first instruction (with a
quick V_DD ramp-up from 0 to 5V (<50µs).
3. Contact the supplier for updated product information.
