4.5.4.3. Address Check Error

Depending on the frame filtering settings, the MAC may check the Destination Address field (i.e., the 1st to 6th bytes) of a received frame against the following conditions:

  • 1 pre-programmed unicast primary MAC address
  • Up to 4 supplementary unicast MAC addresses , if the feature is implemented at design-time and is programmed to enable
  • Multicast address, if the MAC is programmed to accept multicast data frames
  • Broadcast address
  • Pause address, i.e. 48'h0180C2800001 (little-endian)

If at least one type of frame filtering is enabled, and the field does not match with the associated expectation, the frame is dropped.
