<p>The present invention is directed to a pair of on-board DMA channels for use in connection with a single integrated circuit microcontroller. The two DMA channels, which are identical to one another, allow high speed data transfer from one variable memory space to another. As many as 64 Kbytes can be transferred in a single DMA operation. The memory transfer can be between internal data memory, external data memory and/or special function registers (of the type commonly employed in INTEL 8051 microcontrollers).</p> |
