10.13 Receive filter register definitions
10.13.1 Receive Filter Control Register (RxFilterCtrl - 0x5000 0200)
The Receive Filter Control register (RxFilterCtrl) has an address of 0x5000 0200.
Table 165
lists the definition of the individual bits in the register.
10.13.2 Receive Filter WoL Status Register (RxFilterWoLStatus - 0x5000 0204)
The Receive Filter Wake-up on LAN Status register (RxFilterWoLStatus) is a read-only
register with an address of 0x5000 0204.
Table 166
lists the definition of the individual bits in the register.

value
0 AcceptUnicastEn When set to ’1’, all unicast frames are accepted. 0
1 AcceptBroadcastEn When set to ’1’, all broadcast frames are accepted. 0
2 AcceptMulticastEn When set to ’1’, all multicast frames are accepted. 0
3 AcceptUnicastHashEn When set to ’1’, unicast frames that pass the imperfect
hash filter are accepted.
0
4 AcceptMulticastHashEn When set to ’1’, multicast frames that pass the
imperfect hash filter are accepted.
0
5 AcceptPerfectEn When set to ’1’, the frames with a destination address
identical to the
station address are accepted.
0
11:6 - Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
NA
12 MagicPacketEnWoL When set to ’1’, the result of the magic packet filter will
generate a WoL interrupt when there is a match.
0
13 RxFilterEnWoL When set to ’1’, the result of the perfect address
matching filter and the imperfect hash filter will
generate a WoL interrupt when there is a match.
