4. The crystal oscillation settling time depends on the mounted circuit constants, floating capacitance, etc.,
5. Place the crystal resonator and load capacitors C in and C out as close as possible to the chip.
6. Ensure that the crystal resonator connection pin (EXTAL2, XTAL2) wiring is routed as far away as possible
