68 / 87 page  DESIGN GUIDELINES 68/87 Release 1.3 - January 29, 2002 This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. The figure below describes a complete implementation of the external glue logic for DMA Request time-multiplexing and DMA Acknowledge demultiplexing. Like for the interrupt lines, this logic can be simplified when only few DMA channels are used in the application. This glue logic is not needed in Local bus mode as it does not support DMA transfers. Figure 6-11.
