Vcc
Power-on reset circuit
Uses an external capacitor to generate an internal reset signal when power is first supplied.
Low-voltage detection circuit
LVDR: Monitors the power-supply voltage, and generates an internal reset signal when the
voltage falls below a specified value.
LVDI: Monitors the power-supply voltage, and generates an interrupt when the voltage falls
below or rises above respective specified values.
Two pairs of detection levels for reset generation voltage are available: when only the LVDR
circuit is used, or when the LVDI and LVDR circuits are both used.
