OCE
The OCE bit indicates that offset cancellation is enabled. The bq2060 sets this bit after VFC offset
calibration is complete.
0
1
EDV2
Offset calibration is not enabled
Offset calibration is enabled
The EDV2 bit indicates that Voltage() is less than the EDV2 threshold.
0
1
EINT
Voltage() > EDV2 threshold (discharging)
Voltage() ≤ EDV2 threshold
The EINT bit indicates that the VFC has detected a charge or discharge pulse.
0
1
VDQ
No charge/discharge activity detected
Charge/discharge activity detected.
The VDQ bit indicates if the present discharge cycle is valid for an FCC update.
0
1
COK
Discharge cycle is not valid
Discharge cycle is valid
The COK bit indicates the status of the CFC pin of the bq2060.
0
1
DOK
CFC pin is low
CFC pin is high
The DOK bit indicates the status of the DFC pin of the bq2060.
0
1
CVOV
DFC pin is low
DFC pin is high
The CVOV bit indicates that a secondary Li-ion protection limit has been exceeded. It is set if any
individual cell exceeds the programmed high voltage limit, if the pack voltage exceeds the
overvoltage threshold, or if an over-temperature condition occurs. The bit is not latched and merely
reflects the present overvoltage status.
0
No secondary protection limits exceeded
1
A secondary protection limit exceeded
