SSTRING
When this bit is set, it enables an additional 15 characters of storage for both SBS.ManufacturerName( ) and
SBS.DeviceName( ). (Storage is in separate area of data flash)
0 ManufacturerName( ) and DeviceName( ) strings are 11 and 7 characters respectively
1 ManufacturerName( ) and DeviceName( ) strings are 26 and 22 characters respectively
NVCELL
When this bit is set, it forces SBS.VCELL1..4( ) to be accessible via alternative commands.
0 SBS.VCELL1..4( ) available via 0x3c-0x3f
1 SBS.VCELL1..4( ) available via 0x38-0x3b
CCDSG
When this bit is set, it forces SBS.ChargingCurrent( ) to be reported as 0 when SBS.BatteryStatus( )
DISCHARGING is also set.
0 SBS.ChargingCurrent( ) is not modified just because SBS.BatteryStatus( ) DISCHARGING is set.
1 SBS.ChargingCurrent( ) is set to 0 when SBS.BatteryStatus( ) DISCHARGING is set.
SOCL
When this bit is set, it limits both RSOC and ASOC to 99% until a valid charge termination is detected.
0 RSOC and ASOC are not limited.
1 RSOC and ASOC are limited to 99% until charge termination.
CVFC
When this bit is set, it causes SBS.ChargingVoltage( ) to be set to 0 when SBS.BatteryStatus( ) FC = 1.
0 SBS.ChargingVoltage( ) is not modified
1 SBS.ChargingVoltage( ) is set to 0 when FC = 1
DEPFET
When this bit is set, it enables the CHG FET to be turned on when in depleted mode and when the lowest cell
voltage reading is greater than the precharge voltage threshold
0 No FET action taken
1 CHG FET turned on
