/* Date:		26-05-2003

/*-----------------------------------------------------

SPU HLSW 4.0 is positioned as an upgrade of SPU HLSW 3.5, containing the following 

new features:   



  - Link Start-up protocol to DPU modified  

  - Auto SMCS chip reset cycle modified  

  - Disconnect error to DMC link differently handled

  - DMC Link Status convention in the HK modified



These will be explained in the specific sections that follow.





The SPU HLSW Development Team.



Link Start-up protocol to DPU modified

----------------------------------------

The link to DPU is started- up as Master (in the previous version Slave). This is performedto avoid that DPU send NULL tokens to SPU while this latter is in its reset 

cycle. 

Auto SMCS chip reset cycle modified

------------------------------------

SPU HLSW performs SMCS Chip reset every 9 seconds whenever the connection to DPU is not established. 



Disconnect error to DMC link differently handled

-------------------------------------------------

SPU HLSW does not perform SMCS Chip reset when the connection with DMC is lost. However, 

it flags the DMC Link status to OFF in the HK.



DMC Link Status convention in the HK Modified

----------------------------------------------

DMC Link Status in the HK is put to 0xFF whenever the link is ON and to 0x00 in the case 

the connection is started and established. The latter case is also the default value of 

the Link status when the SPU is handed over the HLSW.
