When taken high relative to the voltage on VBAT_SEC, the EN pin shuts down the IC including the boost charger, buck converter and battery management circuitry. It also turns off the PFET that connects VBAT_SEC to VSTOR. This can be described as ship mode, because it will put the IC in the lowest leakage state and provides a long storage period without significantly discharging the battery on VBAT. If there is no need to control EN, it is recommended that this pin be tied to VSS, or system ground.
