DESIGN GUIDELINES
Issue 1.0 - July 24, 2002

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.
