If the supply voltage falls below the voltage detected by the low-voltage detector when LVI operation is enabled, a
The reset status lasts from when a supply voltage drop has been detected until the supply voltage rises above the LVI
The main clock oscillator is stopped during the reset period.
When the LVIMD bit = 0, an interrupt request signal (INTLVI) is generated if a low voltage is detected.
