5 Ship Mode Reentry

To reenter ship mode, all that is required is to drive the GPIO signal. If the push-button is pulled low when the GPIO is turned off, the device will not enter ship mode until the push-button is released. This turns off the BATFET which turns off power to the system. Note that if VIN is present when this occurs, the system is still powered by the input voltage and the battery is not charged. The PGOOD pin can be used to determine when the input is present or absent.
