code, to run with a guarantee that there will be no DMA activity during execution. Note
that a simultaneous interrupt request and DMA transfer request will be resolved in favor
of the DMA transfer request.
The DMA and Ethernet peripherals were optimized to work together; if the Rabbit 4000’s
built-in Ethernet peripheral is used it is expected that two DMA channels will be dedicated
for that purpose.
