Section 22 Realtime Clock (RTC)
22.7.3
If it occurs two or three interrupt source of alarm interrupts(ATI), periodic interrupts(PFI), and
carry interrupts(CUI) at the same time, RTC generates interrupt request as the order of table 22.5.

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.
