ROCR – Regulator Operating Condition Register

• Bit 7 - ROCS: ROC Status

This bit is set when the Voltage Regulator operates in the Battery Pack Short mode, and cleared

otherwise.

• Bit 6:5 - Res: Reserved Bits

These bits are reserved bits and will always read as zero.

• Bit 4 - ROCD: ROC Disable

Setting this bit will disable the Battery Pack Short Detector and VFET will never be disconnected

from the LDO Regulator.

Note that it is NOT recommended to disable the Battery Pack Short Detector by setting the

ROCD bit unless VFET protection is implemented externally.

• Bit 3:2 - Res: reserved Bits

These bits are reserved bits and will always read as zero.

• Bit 1 - ROCWIF: ROC Warning Interrupt Flag

The ROCWIF Flag is set when the Voltage Regulator enters the Battery Pack Short mode. The

flag is cleared by writing logic one to it or by hardware, by executing the corresponding interrupt

handling vector.

• Bit 0 - ROCWIE: ROC Warning Interrupt Enable

The ROCWIE bit enables interrupt caused by the Regulator Operating Condition Warning inter-

rupt flag.
