User manual
10.17.13 Enabling and disabling receive and transmit
Magic Packet filtering is enabled by setting the MagicPacketEnWoL bit of the RxFilterCtrl
register. Note that when doing Magic Packet WoL, the RxFilterEnWoL bit in the
RxFilterCtrl register should be 0. Setting the RxFilterEnWoL bit to 1 would accept all
packets for a matching address, not just the Magic Packets i.e. WoL using Magic Packets
is more strict.
When a magic packet is detected, apart from the WakeupInt bit in the IntStatus register,
the MagicPacketWoL bit is set in the RxFilterWoLStatus register. Software can reset the
bit writing a 1 to the corresponding bit of the RxFilterWoLClear register.
Example: An example of a Magic Packet with station address 0x11 0x22 0x33 0x44 0x55
0x66 is the following (MISC indicates miscellaneous additional data bytes in the packet):
<DESTINATION> <SOURCE> <MISC>
FF FF FF FF FF FF

Enabling and disabling reception
After reset, the receive function of the Ethernet block is disabled. The receive function can
be enabled by the device driver setting the RxEnable bit in the Command register and the
“RECEIVE ENABLE’ bit in the MAC1 configuration register (in that order).
The status of the receive data path can be monitored by the device driver by reading the
RxStatus bit of the Status register.
generation of the RxStatus bit.
