Connected to the internal voltage regulator. Must be
connected through 1uF capacitor to the ground.
Reset pin, active high, must be tied to ground through a 3k3
resistor.
External capacitor for the internal voltage multiplier. Vmult
capacitor must be connected through 2nF to the ground
when VBAT < 3V
