Note 1: Voltage regulator on.
2: VREG ≤ 5.5V, regulator tracks VBAT until VREG < 3.5V.
3: VREG < 3.5V, regulator is off. If the voltage regulator should shut
off due to VREG falling below 3.5V, the VBAT must rise to 6.0V to
turn VREG back on.
4: VREG > 4.0V, voltage regulator tracks VDD, when VREG > 4.0V.
