    The Emergency Shutdown is on pin 15 and pre-charge is on pin 14. There is a pin out error in the datasheet and TRM and they are in the process of being corrected. Please refer to the bq40z60EVM User's Guide for the setups to enable the EMSHUT feature. There is currently a firmware bug that prevents the eternal   pre-charge from working. It will be corrected in the next firmware release.
