TEMPS EXTVCELL WRTEMP LF_EN RSVD GNDSEL GMSEL1 GMSEL0
LEGEND: R/W = Read/Write; R = Read only; -n = value after reset
TEMPS (Bit 7): Enables the external temperature sensor (TS)
1 = External Temperature Sensor is enabled.
0 = Internal temperature sensor is enabled.
EXTVCELL (Bit 6): Enables the external cell voltage translation measurement (VEN, VIN)
1 = External cell voltage translation measurement is used.
0 = Internal cell voltage translation measurement is used.
WRTEMP (Bit 5): Enables host to write the temperature to the gauge
1 = Enabled
0 = Disabled
LF_EN (Bit 4): Enables the Lifetime Data gathering feature
1 = Enabled
0 = Disabled
RSVD (Bit 3): Reserved. Do not use.
GNDSEL (Bit 2): Enables the use of SRN as GND for the ADC conversions
1 = ADC Ground is SRN.
0 = ADC Ground is SRP.
GMSEL1:0 (Bit 1, Bit 0): Enables specific gauging mode
0 0 = Enables ACCUMULATOR mode
0 1 = Enables STATE-OF-HEALTH VOLTAGE CORRELATION mode for LiMnO
2
1 0 = Enables END-OF-SERVICE RESISTANCE CORRELATION mode for LiSOCl
2
1 1 = Invalid setting, do not use.
