Fast Ethernet Controller (FEC)
19.2.4.14 Descriptor Individual Upper Address Register (IAUR)
The IAUR is written by the user. This register contains the upper 32 bits of the 64-bit individual
address hash table used in the address recognition process to check for possible match with the DA
field of receive frames with an individual DA. This register is not reset and must be initialized by
the user.
19.2.4.15 Descriptor Individual Lower Address Register (IALR)
The IALR register is written by the user. This register contains the lower 32 bits of the 64-bit
individual address hash table used in the address recognition process to check for possible match
with the DA field of receive frames with an individual DA. This register is not reset and must be
initialized by the user.
