Bypassing the PDAP FIFO

Question asked by cconrad on Apr 1, 2013

I'm using the PDAP IDP Parallel port in Packing Mode 0 (4 bytes packed into a 32-bit word).  What I really want is to have the packing unit pack 2 bytes into a 16-bit word then push it out to the FIFO, or to have the FIFO bypassed altogether.  Is there some way I can read the packing unit directly in a very synchronous fashion?  The FIFO is such a bother in this case since I am reading and processing my values in a tight assembly loop and the FIFO and packing units create unnecessary delays.

 

Thanks,
