This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
Release 1.3 - January 29, 2002
The
implementation of the external glue logic for DMA
Request time-multiplexing and DMA Acknowledge
demultiplexing. Like for the interrupt lines, this
Figure 6-11. Typical DMA multiplexing and demultiplexing
figure
below
describes
a
complete
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.
