19.1 Functions of Low-Voltage Detector
reset occurs. For details of RESF, see CHAPTER 16 RESET FUNCTION.
19.2 Configuration of Low-Voltage Detector
320
The low-voltage detector (LVI) has following functions.
• Compares supply voltage (V
• Detection levels (nine levels) of supply voltage can be changed by software.
• Interrupt or reset function can be selected by software.
• Operable in STOP mode.
When the low-voltage detector is used to reset, bit 0 (LVIRF) of the reset control flag register (RESF) is set to 1 if
