Notes: 1. Select either the C

side for the frequency adjustment variable capacitor according to requirements
such as the adjustment range, degree of stability, etc.

3. C
in
and C
out
values include floating capacitance due to the wiring. Take care when using a solidearth board.
4. The crystal oscillation stabilization time depends on the mounted circuit constants, floating capacitance, etc.,
and should be decided after consultation with the crystal resonator manufacturer.
5. Place the crystal resonator and load capacitors C
in
and C
out
as close as possible to the chip.
(Correct oscillation may not be possible if there is externally induced noise in the EXTAL2 and XTAL2 pins.)
6. Ensure that the crystal resonator connection pin (EXTAL2 and XTAL2) wiring is routed as far away as possible
from other power lines (except GND) and signal lines.
7. Insert a noise filter in the RTC power supply.

22.7.3 Interrupt
source and request generating order
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.
