RCV DISCRD - Set to discard a packet being received. Will discard packets only in the process of being received. When set prior to the end of receive packet, bit 4 (RXOVRN) of the interrupt status register will be set to indicate that the packet was discarded. Otherwise, the packet will be received normally and bit 0 set (RCVINT) in the interrupt status register. RCV DISCRD is self clearing.

MBO - Must be 1.
