command codes (continued)
The ManufacturerData( ) (0x23);[0x38–0x3a]
Description: This function allows access to the manufacturer data contained in the battery (data). The bq2063
stores seven critical operating parameters in this data area.
Purpose: The ManufacturerData( ) function may be used to access the manufacturer’s data area. The data
fields of this command reflect the programming of five critical EEPROM locations and can be used to facilitate
evaluation bq2063 under various programming sets. The ManufacturerData( ) function returns the following
information in order: Control Mode, Digital Filter, Self-Discharge Rate, Battery Low %, Near Full, and the
pending EDV threshold voltage (low byte and high byte.)
SMBus Protocol: Read Block
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 bq2063 operation. The Pack Status register is the least significant byte of the
word.
The Pack Configuration register reflects how the bq2063 is configured as defined by the value programmed in
Pack Configuration in EE 0x3f. The OTVC bit is cleared when the single midrange voltage correction attempt
is made.
The Pack Status register consists of the following bits:
b7
b6
b5
b4
b3
b2
b1
b0
OCE
EDV2
EINT

OCE
The OCE bit indicates that offset cancellation is enabled. The bq2063 sets this bit after VFC offset calibration
is complete.
0 Offset calibration not enabled
1 Offset calibration enabled
EDV2
The EDV2 bit indicates that pack or cell voltage (program option) 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 not valid
1 Discharge cycle valid
