Legend: RSVD = Reserved

FAS: Status bit that indicates the BQ34Z100 is in FULL ACCESS SEALED state. Active when set.
SS: Status bit that indicates the BQ34Z100 is in the SEALED state. Active when set.
CALMODE: Status bit that indicates the BQ34Z100 calibration function is active. True when set.
Default is 0.
CCA: Status bit that indicates the BQ34Z100 Coulomb Counter Calibration routine is active. Active when set.
BCA: Status bit that indicates the BQ34Z100 Board Calibration routine is active. Active when set.
CSV: Status bit that indicates a valid data flash checksum has been generated. Active when set.
FULLSLEEP: Status bit that indicates the BQ34Z100 is in FULL SLEEP mode. True when set. The state can only be detected by monitoring the power used by the BQ34Z100 because any communication will automatically clear it.
SLEEP: Status bit that indicates the BQ34Z100 is in SLEEP mode. True when set.
LDMD: Status bit that indicates the BQ34Z100 Impedance Track algorithm using constant-power mode. True when set. Default is 0 (CONSTANT CURRENT mode).
RUP_DIS: Status bit that indicates the BQ34Z100 Ra table updates are disabled. True when set.
VOK: Status bit that indicates cell voltages are OK for Qmax updates. True when set.
QEN: Status bit that indicates the BQ34Z100 Qmax updates are enabled. True when set.
