... MCS7830 USB-2.0 to Ethernet Multicast Address Registers (HIF_REG1 to HIF_REG8): The Ethernet MAC receiver accesses these registers every time it receives a multi-cast or a broadcast frame. To check whether the received multi-cast frame is valid, the Ethernet MAC does something called “hash fi ltering”. In hash fi ltering, the CRC-32 (cyclic redundancy check) value is used. The six most signifi cant bits are taken from the 32 bits of the CRC. The Ethernet MAC uses the higher three bits of the six bits as “ ...
