24.1 Functions

24.2 Configuration
736
The low-voltage detector (LVI) has the following functions.
• If the interrupt occurrence at low-voltage detection is selected, the low-voltage detector compares the supply
• If the reset occurrence at low-voltage detection is selected, the low-voltage detector generates an interrupt reset
• The level of the supply voltage to be detected can be changed by software (in two steps).
• Interrupt or reset signal can be selected by software.
• Can operate in STOP mode.
If the low-voltage detector is used to generate a reset signal, the RESF.LVIRF bit is set to 1 when the reset signal is
