23.1 Functions of Low-Voltage Detector
reset occurs. For details of RESF, refer to CHAPTER 20 RESET FUNCTION.
23.2 Configuration of Low-Voltage Detector
410
The low-voltage detector (LVI) has following functions.
When the low-voltage detector is used to reset, bit 0 (LVIRF) of the reset control flag register (RESF) is set to 1 if
The block diagram of the low-voltage detector is shown below.
