When the SC614 is first enabled, it starts up in Sleep Mode, with the registers at their reset values and the charge
pump off. The bandgap reference will be operating, the input voltage will be monitored for UVLO and the serial
interface will be monitored for any activity. This is the lowest power state for the device where it can be
communicated with. In order to activate the charge pump it is necessary to clear the Sleep bit to 0 to enter Run
Mode. When in Run Mode the charge pump is activated in 1x mode with VOUT = 1.5V, and all of the optional
functions of the device may be accessed.
