The MACB module implements a 10/100 Ethernet MAC compatible with the IEEE 802.3 stan-
dard using an address checker, statistics and control registers, receive and transmit sub-
modules, and a DMA interface.
The address checker recognizes four specific 48-bit addresses and contains a 64-bit hash regis-
ter for matching multicast and unicast addresses. It can recognize the broadcast address of all
ones, copy all frames, and act on an external address match signal.
The statistics register sub-module contains registers for counting various types of events associ-
ated with transmit and receive operations. These registers, along with the status words stored in
the receive buffer list, enable software to generate network management statistics compatible
with IEEE 802.3.
