Output: Block data—data that reflects EEPROM programming as assigned by the manufacturer with maximum
length of 7 characters (7+length byte).
Pack Status and Pack Configuration (0x2f); [0x2f]
This function returns the Pack Status and Pack Configuration registers. The Pack Status register contains a
number of status bits relating to bq2060A operation. The Pack Status register is the least significant byte of the
word. The Pack Configuration register is the most significant byte of the word. The byte reflects how the
bq2060A is configured as defined by the value programmed in Pack Configuration in EE 0x3f.
The Pack Status Register consists of the following bits:
b7 b6 b5 b4 b3 b2 b1 b0
OCE EDV2 EINT VDQ COK DOK CVOV CVUV
OCE
The OCE bit indicates that offset cancellation is enabled. The bq2060A sets this bit after VFC offset calibration is
complete.
0 Offset calibration is not enabled
1 Offset calibration is enabled
EDV2
The EDV2 bit indicates that Voltage() is less than the EDV2 threshold.
0 Voltage() > EDV2 threshold (discharging)
1 Voltage() ≤ EDV2 threshold
EINT
The EINT bit indicates that the VFC has detected a charge or discharge pulse.
0 No charge/discharge activity detected
1 Charge/discharge activity detected.
VDQ
The VDQ bit indicates if the present discharge cycle is valid for an FCC update.
0 Discharge cycle is not valid
1 Discharge cycle is valid
COK
The COK bit indicates the status of the CFC pin of the bq2060A.
0 CFC pin is low
1 CFC pin is high
DOK
The DOK bit indicates the status of the DFC pin of the bq2060A.
0 DFC pin is low
