Functional description:
===============================================================================================
This example configures the processor state from PS4 to sleep, where processors will  wakes up 
from deep sleep to PS4 state based on RTC seconds interrupts where code is downloaded to flash memory
This example also demonstrates how to configure  RTC milli second interrupts,Deep sleep timer 
interrupts,RTC Alarm interrupts,UULP_GPIO_2 interrupts as a wakeup sources based on the partcular
define uncommented from line number 30 to 34.
