MK5027 Features

* of the MK5027 is its buffer management which includes on-chip DMA. This feature allows users to handlq multiple packets of receive and transmit data at a time. (A conventional data linkcontrol chip plus a separate DMA chip would handle data for only a single block at a time.) The MK5027 may be used
