SLUSB20C November 2012 – November 2021
This mode is a halted-CPU state that occurs when an adapter, or other power source, is present to power the fuel gauge (and system), but no battery has been detected. When battery insertion is detected, a series of initialization activities begin, which include: OCV measurement, setting the Flags() [BAT_DET] bit, and selecting the appropriate battery profiles.
Some commands, issued by a system processor, can be processed while the fuel gauge is halted in this mode. The gauge wakes up to process the command, then returns to the halted state awaiting battery insertion.
