Note
Cautions 1. To stop LVI, be sure to clear (0) the LVION bit by using a 1-bit memory manipulation instruction.
4.
2. Input voltage from the external input pin (EXLVI) must be EXLVI < V
3. When LVI is used in interrupt mode (LVIMD = 0) and the LVISEL bit is set to 0, an interrupt
4. To read the LVIM register after writing this register, secure the time of one or more clock.
The LVIF flag value for these periods may be set/cleared regardless of the voltage level, and can
therefore not be used. Also, the LVIIF interrupt request flag may be set to 1 in these periods.
When the LVION bit is set to 1, operation of the comparator in the LVI circuit is started. Use software to
wait for the following periods of time, between when the LVION bit is set to 1 and when the voltage is
confirmed with LVIF flag.
