This register establishes the RX and TX operation modes and controls for address filtering and packet

filtering.

BITS

30-24

DESCRIPTION

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.

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.
