The archive provides 1 code example:

Directory $(VDSP)\BF533_EZKIT_Hibernation_Example illustrates one example that runs with the standard ADSP-BF533 EZ-KIT Lite board. Anyone with this standard hardware can run this example.  The engineer can see how hibernation mode works utitlizing the EZKIT built-in regulator, 3.3V I/O and standard SDRAM (non-mobile).  To see the advanced features such as 1.8V I/O operation with an external voltage regulator, please see PMP_Hibernation_Example.zip

There are 4 main threads:
1.Main Thread (priority 5)  Configures the peripherals and creates the Hibernate and BlinkLED threads.
2.BlinkLED Thread (priority 6)  Simply blinks LED4 15 times on the PMP reference board.
3.Hibernate Thread (priority 7)  Shuts down peripherals, saves the state of system into SDRAM and puts the processor into hibernate mode.  Before the thread goes into hibernate mode, the real time clock (RTC) is configured and SDRAM is placed into self-refresh mode.  Upon wakeup, the processor returns to this thread and the peripherals are re-configured.
4. Idle Thread (lowest priority thread)  default VDK thread.  The processor executes this thread when there in nothing to do. 

**Note that the engineer must flash these examples into the flash on the EZKIT to allow for context restore operations at bootup.
