The fuel gauge has three power modes: NORMAL, SLEEP, and FULLSLEEP. In NORMAL mode, the fuel gauge is fully powered and continually refreshes its dataset every 1 second. In SLEEP mode, the fuel gauge CPU is halted and frequency of data measurement is reduced to 20-second intervals for increased power savings when the system is in a standby state. In FULLSLEEP mode, the fuel gauge disables its high frequency oscillator (HFO) for highest operating power savings. The relationship between these modes is shown in Figure 4-1. Details are described in Section 4.1.1 through Section 4.1.3.
