4. The crystal oscillation stabilization time depends on the mounted circuit constants, floating capacitance, etc.,
5. Place the crystal resonator and load capacitors C
6. Ensure that the crystal resonator connection pin (EXTAL2 and XTAL2) wiring is routed as far away as possible
7. Insert a noise filter in the RTC power supply.
