RECEIVE CONFIGURATION REGISTER (RCR)
This register determines operation of the DP83907 during reception of a packet and is used to program what types of packets to
accept
Note D2 and D3 are ‘‘OR’d’’ together i e if D2 and D3 are set the DP83907 will accept broadcast and multicast addresses as well as its own physIcal address To
establish full promiscuous mode bits D2 D3 and D4 should be set In addition the multicast hashing array must be set to all 1’s in order to accept all multicast
addresses

SAVE ERRORED PACKETS
ACCEPT RUNT PACKETS This bit allows the receiver to accept packets that are smaller than 64
bytes The packet must be at least 8 bytes long to be accepted as a runt
ACCEPT BROADCAST Enables the receiver to accept a packet with an all 1’s destination address
ACCEPT MULTICAST Enables the receiver to accept a packet with a multicast address all multicast
addresses must pass the hashing array
PROMISCUOUS PHYSICAL Enables the receiver to accept all packets with a physical address
