Notes 4.
Cautions 1. To stop LVI, follow either of the procedures below.
5.
2. Input voltage from external input pin (EXLVI) must be EXLVI < V
3. If LVI operation is disabled (clears LVION) when LVI is used in interrupt mode (LVIMD = 0),
4. For 78K0/KY2-L and 78K0/KA2-L, be sure to clear bit 2 to 0.
When LVION is set to 1, operation of the comparator in the LVI circuit is started. Use software to wait
for an operation stabilization time (10
stabilized. After the operation stabilizes, an external input (minimum pulse width: 200 s) of 200 s
or more is required until LVIF is set (1) after the voltage drops to the LVI detection voltage or less.

When using 8-bit memory manipulation instruction: Write 00H to LVIM.
When using 1-bit memory manipulation instruction: Clear LVION to 0.
