 * MSP432E4 Example for Deep Sleep Mode entry and wakeup using GPIO
 *
 * Description: The application code puts the device in deep sleep mode with
 * clock enabled only for the GPIO in deep sleep mode and memory in standby.
 * During Active state (RUN Mode), the LED D1 is switched ON. When there is no
 * activity the device is put into deep sleep mode and LED D1 is switched OFF.
 * During Deep sleep the clock source if LFIOSC, the core voltage is reduced
 * to 0.9V and memory banks are put in low power state. When the user presses
 * USR_SW2 the device is woken up and the LED D1 switches ON.
