29<H2>Description</H2>
30<P>Starts the new DMA once it has been configured.</P>
31<P>This function starts DMA using the configuration of the current new DMA register. Specifically, it sets the enable bit of the new DMA specified by <B><I>ndmaNo</I></B> to 1. Other DMA-related registers must be set in advance.</P>
32<P>DMA can be configured in advance with the <CODE><A href="MI_NDmaCopy.html">MI_NDmaCopy*</A>, <A href="MI_NDmaFill.html">MI_NDmaFill*</A>, <A href="MI_NDmaClear.html">MI_NDmaClear*</A>, <A href="MI_NDmaSend.html">MI_NDmaSend*</A>, <A href="MI_NDmaRecv.html">MI_NDmaRecv*</A>, and <A href="MI_NDmaPipe.html">MI_NDmaPipe*</A></CODE> functions whose names include &quot;_SetUp.&quot; For details, see the various function references.</P>
33<P>Originally, this function was created to configure only the necessary registers and restart DMA after a DMA operation had completed. That is why this function includes &quot;Restart&quot; in its name.</P>
34<H2>Internal Operation</H2>
35<P>Uses the new I/O DMA registers.</P>
