The low-voltage detector (LVI) has following functions.
• Compares supply voltage (V
• Detection levels
• Interrupt or reset function can be selected by software.
• Operable in STOP mode.
Note Detection levels of supply voltage differ as follows.
When the low-voltage detector is used to reset, bit 0 (LVIRF) of the reset control flag register (RESF) is set to 1 if
