Field
Description
31–0 The lower 32 bits of the 64-bit hash table used in the address recognition process for receive frames with a unicast
IADDR2 address. Bit 31 of IADDR2 contains hash index bit 31. Bit 0 of IADDR2 contains hash index bit 0.
17.4.17 Descriptor Group Upper Address Register (GAUR)
GAUR contains the upper 32 bits of the 64-bit hash table used in the address recognition process for
receive frames with a multicast address. You must initialize this register.

Field
Description
31–0 The GADDR1 register contains the upper 32 bits of the 64-bit hash table used in the address recognition process for
GADDR1 receive frames with a multicast address. Bit 31 of GADDR1 contains hash index bit 63. Bit 0 of GADDR1 contains
hash index bit 32.
