The device is in the
process of calibrating
CC offset while the
CCA bit is set. The
CCA bit will clear and
then the device will

3.6 Board Offset
Use MAC commands for Board Offset calibration. The host system does not need to write information to
the DF. The host system must ensure that the fuel gauge is UNSEALED. See CONTROL_STATUS:
0x0000 for the description of the CONTROL_STATUS[CCA] and [BCA] bits.
NOTE: While the device is calibrating the Board Offset, the host system should not read the
CONTROL_STATUS() register at a rate greater than once every 0.5 seconds and no current
should be flowing.
The step labeled Enter CALIBRATION Mode refers to Section 3.3, Enter CALIBRATION
Mode.
The step labeled Exit CALIBRATION Mode refers to Section 3.11, Exit CALIBRATION
Mode.
