DESCRIPTION
Returns the IC part number.
Returns the firmware version.
Returns the hardware version
Generates a checksum of the full Data Flash (DF) array
Enters Sealed mode with limited access to the extended SBS functions and data flash
space
0 = Disables logging of lifetime data to non-volatile memory and disables capacitor
balancing
1 = Enables logging of lifetime data to non-volatile memory and enables capacitor
balancing
Returns the value of the Instruction Flash (IF) checksum
This write function instructs the bq33100 to enter a capacitance learning
cycle(Capacitance Update).
This write function instructs the bq33100 to reset the capacitance learned values
(Capacitance) to initial default values.
This write function instructs the bq33100 to enter a capacitance learning
cycle(Capacitance Update) and update Initial values for Capacitance and ESR
