CHAPTER 16 LOW-VOLTAGE DETECTOR

16.1 Functions of Low-Voltage Detector

The low-voltage detector (LVI) has following functions.

•

Compares supply voltage (V

) and detection voltage (V

LVI

), and generates an internal interrupt signal or

internal reset signal when V

< V

LVI

•

Detection levels (ten 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

reset occurs. For details of RESF, refer to CHAPTER 14 RESET FUNCTION.

16.2 Configuration of Low-Voltage Detector

The block diagram of the low-voltage detector is shown in Figure 16-1.
