Instructs the fuel gauge to set the CONTROL_STATUS [FULLSLEEP] bit to 1. The gauge enters the FULLSLEEP power mode after the transition to the SLEEP power state is detected. In FULLSLEEP mode less power is consumed by disabling an oscillator circuit used by the communication engines. For HDQ communication one host message is dropped, while the oscillator restarts if communication is initiated during FULLSLEEP and may need to be repeated. For I2C communications, the first I2C message incurs a 6- to 8-ms clock stretch while the oscillator is started and stabilized. A communication to the device in FULLSLEEP forces the part back to the SLEEP mode.
