The low-voltage detector (LVI) has the following functions.
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
The block diagram of the low-voltage detector is shown below.
• If the interrupt occurrence at low voltage detection is selected, the low-voltage detector continuously compares the
• If the reset occurrence at low voltage detection is selected, the low-voltage detector generates an interrupt reset
• Interrupt or reset signal can be selected by software.
• Can operate in STOP mode.
