In this case, the internal voltage regulator is not used. The operation speed of the circuit can be increased with
increasing supply voltage but the supply current will also increase. The capacitor on VMULT has to be connected
only when VBAT<3V. In this case, the supply voltage can decrease down to 2.15V. Beware however that the
