LVIIF flag
LVIF flag
The LVIMK flag is set to “1” by reset signal generation.
The interrupt request signal (INTLVI) is generated and the LVIF and LVIIF flags may be set (1).
If LVI operation is disabled when the input voltage of external input pin (EXLVI) is less than or equal to
the detection voltage (V
