LVISEL flag
LVIMD 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 (clears the LVION bit) when the input voltage of the external input pin (EXLVI) is
less than or equal to the detection voltage (V
the LVIIF flag may be set to 1.
