It should be able to...  you'll have to know the physical addresses of the 
board and buffers in order to setup the trace conditions... I was able to 
specifically watch read writes to certain registers and not others... 
The conditional programming on the HP logic analyzers is a bit, um,
unusual, at least from this software engineers viewpoint...

never tried one.
