49<H2>Description</H2>
50<P>Uses the new DMA to copy using a timer. DMA will run when a timer interrupt occurs.</P>
51<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>
52<P>The timer is not set within the function. Care must be taken when setting timers in the application because some are used by the system.</P>
53<H2>Internal Operation</H2>
54<P>Accesses the new DMA register.</P>
