Write a "1" to this + property to arm a special "ship" mode that extends shelf life + by reducing the leakage to about 2.8 microamps. The chip will + remain in this mode (and no longer respond to I2C commands) + until some external power-supply is attached raising the input + voltage above 1V. It will then automatically revert to "0". + Writing a "0" to the property cancels the "ship" mode request. + The ship mode, when armed, activates once the input voltage + drops below 1V. + + Access: Read, Write + + Valid values: 0 (disable) or 1 (enable) -- cgit v1.2.3
