38  * wake the system up back into direct-run mode.
43  * SDRAM will still be accessible in direct-run mode. In DDR based systems,
44  * a transition to direct-run mode will stop all DDR accesses (no clocks).

50  *  Backup a small area of IRAM used for the suspend code
51  *  Copy suspend code to IRAM
53  *  Places DRAMs in self-refresh mode
54  *  Enter direct-run mode
57  *  Enter halt mode - CPU and buses will stop
58  *  System enters direct-run mode when an enabled event occurs
60  *  Run mode is entered
