Abstract
A microcontroller implements a buffer descriptor ring direct memory access (DMA) unit that can transmit a chained series of buffers without processor intervention. The buffers, however, include an interrupt on end-of-buffer flag that allows for an interrupt to be generated at the end of each buffer on a buffer-by-buffer basis.
