CPE
The CPE bit enables/disables PEC transmissions to the smart battery charger for master mode messages.
0
No PEC byte on broadcasts to charger
1
PEC byte on broadcasts to charger
SM
The SM bit enables/disables master mode broadcasts by the bq2083V1P2.
0
Broadcasts to host and charger enabled
1
Broadcasts to host and charger disabled
If the SM bit is set, modifications to bits in BatteryMode( ) do not re-enable broadcasts.
CC1CC0
The CC bits configure the bq2083V1P2 for the number of series cells in the battery pack.
11 Configures the bq2083V1P2 for four series cells
10 Configures the bq2083V1P2 for three series cells

CSYNC
In usual operation of the bq2083V1P2, the CSYNC bit is set so that the coulomb counter is adjusted when a fast
charge termination is detected. In some applications, especially those where an externally controlled charger is
used, it may be desirable
not
to adjust the coulomb counter. In these cases the CSYNC bit should be cleared.
0
1
The bq2083V1P2 does not alter RM at the time of a valid charge termination.
The bq2083V1P2 updates RM with a programmed percentage of FCC at a valid charger termination.
SC
The SC bit enables learning cycle optimization for a Smart Charger or independent charge.
1
0
Learning cycle optimized for independent charger
Learning cycle optimized for Smart Charger
CEDV
The CEDV bit determines whether the bq2083V1P2 implements automatic EDV compensation to calculate the
EDV0, EDV1, and EDV2 thresholds base on rate, temperature, and capacity. If the bit is cleared, the
bq2083V1P2 uses the fixed values programmed in data flash for EDV0, EDV1, and EDV2. If the bit is set, the
bq2083V1P2 calculates EDV0, EDV1, and EDV2.
0
1
EDV compensation disabled
EDV compensation enabled
EDVV
The EDVV bit selects whether EDV termination is to be done with regard to voltage or the lowest single-cell voltage.
0
EDV conditions determined on the basis of the lowest single-cell voltage
1
EDV conditions determined on the basis of Voltage( )
OVSEL
The OVSEL bit determines if safety over voltage is based on pack or highest cell voltages.
0
Safety over voltage based on pack voltage
1
Safety over voltage based on highest cell voltage multiplied by the number of cells and then compared to
the safety voltage
