Each of the eight entries in the multicast address filter logic has individual registers
to hold its 48-bit multicast address. The multicast address for each entry is split
between two registers. Each entry has a register that contains the lower 32 bits of
the multicast address and a separate register that contains the upper 16 bits of the
address. For an explanation of the synchronization scheme used for these registers,
see “Clock synchronization” on page 276.
