11.5.17 Hash Table High (HTUR)
The HTUR register, Figure 11-21, contains the upper 32 bits of the 64-bit hash table used
in the address recognition process for receive frames with a multicast address.
This register is not reset and must be initialized by the user prior to operation.
11.5.18 Hash Table Low (HTLR)
The HTLR register, Figure 11-22, contains the lower 32 bits of the 64-bit hash table used
in the address recognition process for receive frames with a multicast address.
This register is not reset and must be initialized by the user prior to operation.
