BPIFR – Battery Protection Interrupt Flag Register
• Bit 0 - CHCIE : Charger High-current Protection Activated Interrupt
The CHCIE bit enables interrupt caused by the Charge High-current Protection Activated
Interrupt.
• 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 – DHCIF: Disharge High-current Protection Activated Interrupt
Once Discharge High-current violation is detected, DHCIF becomes set. The flag is cleared by
writing a logic one to it.
• Bit 0 – CHCIF: Charge High-current Protection Activated Interrupt
Once Charge High-current violation is detected, CHCIF becomes set. The flag is cleared by writ-
ing a logic one to it.
