Note
Cautions 1. To stop LVI, follow either of the procedures below.
4.
2. Input voltage from external input pin (EXLVI) must be EXLVI < V
3. When LVI is used in interrupt mode (LVIMD = 0) and LVISEL is set to 0, an interrupt request
The LVIF 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 LVION 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 LVION is set to 1 and when the voltage is confirmed
with LVIF.
• When using 8-bit memory manipulation instruction: Write 00H to LVIM.
• When using 1-bit memory manipulation instruction: Clear LVION to 0.
signal (INTLVI) that disables LVI operation (clears LVION) when the supply voltage (V
