20.8.8 BPIMSK – Battery Protection Interrupt Mask Register

• Bit 7:5 – Res: Reserved Bits

These bits are reserved and will always read as zero.

• Bit 4 – SCIE: Short-circuit Protection Activated Interrupt

The SCIE bit enables interrupt caused by the Short-circuit Protection Activated Interrupt.

• Bit 3 – DOCIE: Discharge Over-current Protection Activated Interrupt

The DOCIE bit enables interrupt caused by the Discharge Over-current Protection Activated

Interrupt.

• Bit 2 – COCIE: Charge Over-current Protection Activated Interrupt

The COCIE bit enables interrupt caused by the Charge Over-current Protection Activated

Interrupt.

• Bit 1:0 – Res: Reserved Bits

These bits are reserved and will always read as zero.

20.8.9 BPIFR – Battery Protection Interrupt Flag Register

• Bit 7:5 – Res: Reserved Bit

These bits are reserved and will always read as zero.

• Bit 4 – SCIF: Short-circuit Protection Activated Interrupt

Once Short-circuit violation is detected, SCIF becomes set. The flag is cleared by writing a

logic one to it.

• Bit 3 – DOCIF: Discharge Over-current Protection Activated Interrupt

Once Disharge Over-current violation is detected, DOCIF becomes set. The flag is cleared by

writing a logic one to it.

• Bit 2 – COCIF: Charge Over-current Protection Activated Interrupt

Once Charge Over-current violation is detected, COCIF becomes set. The flag is cleared by

writing a logic one to it.

• Bit 1:0 – Res: Reserved Bit

These bits are reserved and will always read as zero.
