NOTES:
8. After TWL2213 has finished charging, these values are set to 0.
9. During CHGSTR H, ADC enables and periodically keeps functioning.
10. During charging mode, ADVB is enabled automatically.
11. Charging mode is not necessary to set enable for function.
12. External microprocessor must set CHGSTR bit to 0 when NOCHG = 1
