RSVD = Reserved. Default = 0.
SOC1_EN = Enables alert for State-of-Charge-Threshold 1 (SOC1 Set) reached. True when set. Default is 1.
OCC_EN = Enables alert for Over Current Charge Condition when set to 1. Default is 0.
OCD_EN= Enables alert for Over Current DISCHARGE Condition when set to 1. Default is 0.
BatAlertStatus(): 0x6C/0x6D
The BatAlertStatus() register allows reading the safety conditions that triggered the alert. If the Pack
Configuration [CLR_READ] is set to 1, BatAlertStatus() will be reset, and the alert assertion removed
immediately. Otherwise, the BatAlertStatus() flags will clear only after the safety flag has reset, and the alert
assertion clears once all flags in BatAlertStatus() have cleared.

The following functions can be detected for fault conditions when set in the BatAlert Configuration register. The
fault can be indicated on Alert pin (if configured) but not differentiated because of the OR logic.
UTC = Detected Under Temperature Charge Current when set to 1.
UTD = Detected Under Temperature Discharge Current when set to 1.
RSVD = Reserved. Default = 0.
OTC = Detected Over Temperature Charge Current when set to 1.
OTD = Detected Over Temperature Discharge Current when set to 1.
BATHI= Detected Battery High Condition when set to 1.
BATLO = Detected Battery Low Condition when set to 1.
RSVD = Reserved. Default = 0.
SOC1 = Detected State-of-Charge-Threshold 1 (SOC1 Set) reached.
OCC = Detected Over Current Charge Condition when set to 1.
OCD= Detected Over Current DISCHARGE Condition when set to 1.
