DMODE
The DMODE bit determines whether the LED outputs will indicate AbsoluteStateOfCharge() or
RelativeStateOfCharge()
0
LEDs reflect AbsoluteStateOfCharge()
1
LEDs reflect RelativeStateOfCharge()
SEAL
The SEAL bit determines the SMBus access state of the bq2060 on reset
0
SMBus commands (0x00–0xff) are accessible for both read and write.
1
SMBus read access is limited to commands (0x05–0x1c) and (0x20–0x23). SMBus read/write
access is limited to commands (0x00–0x04), (0x2f), and (0x3c–0x3f).
CSYNC
In usual operation of the bq2060, 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
The bq2060 does not alter RM at the time of a valid charge termination.
1
The bq2060 updates RM with a programmed percentage of FCC at a valid charge termination.
CEDV
The CEDV bit determines whether the bq2060 implements automatic EDV compensation to calculate the EDV0,
EDV1, and EDV2 thresholds based on rate, temperature, and capacity. If reset, the bq2060 uses the fixed values
programmed in EEPROM for EDV0, EDV1, and EDV2. If set the bq2060 calculates EDV0, EDV1, and EDV2.
0
EDV compensation disabled
1
EDV compensation enabled
VCOR
The VCOR bit enables the midrange voltage correction algorithm. When set, the bq2060 compares the pack
voltage to RM and may adjust RM according to the values programmed in VOC25, VOC50, and VOC75.
0
Midrange corrections disabled
1
Midrange corrections enabled
CHEM
The CHEM bit configures the bq2060 for nickel packs (NiCd or NiMH) or Li-ion packs. When set, the bq2060
employs the configuration parameters in EEPROM designated for Li-ion. When not set, the bq2060 employs the
configuration parameters designated for nickel.
