Register Description
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 – Reserved
These bits are reserved 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 – Reserved
These bits are reserved 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.
