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 bq2060A 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 bq2060A, 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 bq2060A does not alter RM at the time of a valid charge termination.
1 The bq2060A updates RM with a programmed percentage of FCC at a valid charge termination.
CEDV
The CEDV bit determines whether the bq2060A implements automatic EDV compensation to calculate the
EDV0, EDV1, and EDV2 thresholds base on rate, temperature, and capacity. If reset, the bq2060A uses the
fixed values programmed in EEPROM for EDV0, EDV1 and EDV2. If set, the bq2060A 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 bq2060A 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 bq2060A for nickel packs (NiCd or NiMH) or Li-ion packs. When set, the bq2060A
employs the configuration parameters in EEPROM designated for Li-ion. When not set, the bq2060A employs
the configuration parameters designated for nickel.
0 The bq2060A uses nickel configuration parameters.
1 The bq2060A uses Li-ion configuration parameters.
LCC0 and LCC1
The LCC0 and LCC1 bits configure the cell voltage inputs (VCELL_1–4).
