[Efi332] Question regarding PMMX

[BowTieVette at aol.com]

Paul,
There is nothing on this issue (I don't use the cam synch  feature) but there 
are some other errata and notes on the 58XX functions  here that you may want 
to be aware of:

(http://efi332.sourceforge.net/TPU.htm) 
 
perhaps your notes should go here..

I found the problem.
 
While the documentation that I have for the PMMX  function indicates a HSRR 
value of b01 for a CAM Sync request, the micro-code  for the PMMX function (doc 
and code from the FTP archive) actually recognizes  b10 as a CAM sync request.
 
This little tid bit should be helpful to anyone  writing their own source.
 
Also, it would be a good idea to add a note  reflecting this change in the 
TPU function doc (though I don't know who would  do that).

Subject: [Efi332] Question regarding  PMMX


All,
 
Are there any particular "procedural  requirements" for sending a CAM Synch 
request (HSRR = 1) to the PMMX  function? (like disabling all linked channels, 
etc.)
 
The reason that I ask is because I am testing  my CAM Synch logic, and when I 
set the associated HSRR bits to b01,  everything on the TPU stops. The only 
requirement that I can find in the  documentation that I have is that the CAM 
Synch request should be made when  PMMX is in the synchronized state (which it 
is at the point that I am making  the request).
 
Any ideas?
 
-Paul
