23.1 Functions
generated. For details of RESF register, see CHAPTER 22 RESET FUNCTIONS.
23.2 Configuration
The low-voltage detector (LVI) has the following functions.
• Compares the supply voltage (V
• The level of the supply voltage to be detected can be changed by software (in two steps).
• An interrupt request signal (INTLVIL, INTLVIH) or internal reset signal (LVIRES) can be selected.
• Can operate in STOP mode.
• Operation can be stopped by software.
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
