The DMA request (DMARx asserted) signals indicated in Figure 5-18 and Figure 5-19 are not required. The following changes are needed:
  • Remove the DMARx signal from both figures.
  • The captions for these figures should change to:
    • Figure 5-18. FLYBY Write from I/O Device to SDRAM
    • Figure 5-19. FLYBY Read from SDRAM to I/O Device
  • Change the first bullet in the description of figure 5-18 to:
    • Back to back quad-word writes from I/O Device to SDRAM occur.
  • Change the first bullet in the description of figure 5-19 to:
    • Back to back quad-word reads from SDRAM to I/O Device occur.
