44<H2>Description</H2>
45<P>Uses the new DMA to copy using a card interrupt. DMA will run when a card interrupt occurs.</P>
46<P>It uses the new DMA to perform copies in word (4-byte) units. Both the transfer source address (<B><I>src</I></B>) and the transfer destination address (<B><I>dest</I></B>) must be 4-byte aligned. The transfer size (<em><strong><code>size</code></strong></em>) needs to be a multiple of 4.</P>
47<H2>Internal Operation</H2>
48<P>Accesses the new DMA register.</P>
