The Station Address Filter register contains several filter controls. The register is
located in the station address logic (see “Station address logic (SAL)” on page 264).
All filtering conditions are independent of each other. For example, the station
address logic can be programmed to accept all multicast frames, all broadcast
frames, and frames to the programmed destination address.
