 * 
 * 13    1/30/04 11:52a Stephaneh
 * Integrated CDG Feature
 * 
 * 12    8/27/03 10:57a Leonh
 * add the debug function for get the satus if the semaphore is set
 * 
 * 11    03-07-29 20:02 Fwang
 * Add SEM_ADP
 * Enable USED_GET_TID
 * 
 * 10    03-06-17 18:27 Admin
 * Merge for ExinoII project
 * 
 * 9     03-04-17 11:53 Jerryc
 * share reflasher burner APIS with capture_logo and store_ps_in_flash
 * features.
 * 
 * 10    24/05/02 16:53 Nirm
 * - Enabled Event-Flags.
 * 
 * 9     23/04/02 9:27 Nirm
 * - Added dependency in "Config.h".
 * 
 * 8     31/03/02 9:31 Nirm
 * Increased number of Tasks and Mailboxes.
 * 
 * 7     27/03/02 8:32 Nirm
 * - Corrected typo in the name of InterruptEnable().
 * 
 * 6     26/03/02 23:18 Nirm
 * - Changed the value of RTOS_TICK_MS.
 * 
 * 5     26/02/02 21:18 Nirm
 * Enabled use of Lock/Unlock CPU.
 * 
 * 3     1/15/02 2:18p Tomasp
 * - code cleanup
 * - removed compilation warnings
 * - functions _disable and _enable replaced by InterruptDisable and
 * InterruptEnable to prevent name colisions with function in embedded.h
 * 
 * 2     9/01/02 18:31 Nirm
 * Corrected Include-Paths.
