Notes:
1. Some defaults are chemistry dependant. See the detailed register descriptions for more information.
2. Charger setting registers (sub-addresses 0x1A through 0x2D) are only writable if the CHEM pins are configured for a programmable chemistry option.
If the CHEM pins are configured for a fixed chemistry option, the charger setting registers are read only.
