DESCRIPTION
31
Receive All Mode (RXALL). When set, all incoming packets will be received and passed on to the
address filtering Function for processing of the selected filtering mode on the received frame. Address
filtering then occurs and is reported in Receive Status. When reset, only frames that pass Destination
Address filtering will be sent to the Application.
30-24
23
Reserved
Disable Receive Own (RCVOWN). When set, the MAC disables the reception of frames when TXEN
is asserted. The MAC blocks the transmitted frame on the receive path. When reset, the MAC receives
all packets the PHY gives, including those transmitted by the MAC.This bit should be reset when the
Full Duplex Mode bit is set.
