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.
nCSOUT is driven low by the LAN91C111 when a valid access to the EXTERNAL REGISTER range
occurs.
