having obtained the match in this example). Note the following:

Figure 7-3: Normal Frame Reception: Address Filter Match
illustrates Legacy frame reception for an error free frame in which at least one of
Each of the eight individual MAC Header Filters has a corresponding bit within the
legacy_rx_filter_match[7:0] bus. If the corresponding MAC Header Filter
obtains a match, the relevant bit will be asserted. This will be fully aligned with the
legacy_rx_data_valid signal during frame reception.
Every bit within the legacy_rx_filter_match[7:0] bus will be asserted for
frame reception in which the Frame Destination Address (DA) contained a Broadcast
Address.
Every bit within the legacy_rx_filter_match[7:0] bus will be asserted when
the MAC Header Filter is operating in Promiscuous Mode (see
Register").
