NOTES:
7. After the TWL2214CA device has finished charging, these values are set to 0.
8. During CHGSTR H, ADC enables and periodically keeps functioning.
9. During charging mode ADVB is enabled automatically.
10. Charging mode is not necessary to set enable for function.
11. External microprocessor must set CHGSTR bit to 0 when NOCHG = 1

NOTES: 12. CONT = H, REG6 is dependent on D7 to enable. CONT = L, REG6 is independent of D7, always on after power up.
13. VG3_EN = 1, forces VG3 signal to Low. VG3_EN = 0, VG3 signal is at normal condition. Control of this bit is valid only when the adapter is connected.
