Figure 4. DMA Unit
DMA Priority
DMA transfers have a higher priority than CPU transfers, with the exception of word accesses to odd
memory locations or between locked memory addresses. The CPU cannot access memory during a DMA
transfer and a DMA transfer cannot be suspended by an interrupt request. Continuous DMA activity will
thus cause interrupt latency to suffer. However, an NMI request halts any DMA activity, enabling the
CPU to respond promptly to the request.
