182 / 262 page  ST72561 182/262 beCAN CONTROLLER (Cont’d) Figure 103. Filtering Mechanism - example The example above shows the filtering principle of the beCAN. On reception of a message, the iden- tifier is compared first with the filters configured in identifier list mode. If there is a match, the mes- sage is stored in the FIFO and the index of the matching filter is stored in the Filter Match Index. As shown in the example, the identifier matches with Identifier #2 thus the message content and MFMI 2 is stored in the FIFO. If there is no match, the incoming identifier is then compared with the filters configured in mask mode. If the identifier does not match any of the identifi- ers configured in the filters, the message is dis- carded by hardware without software intervention. Message Discarded Identifier 0 Identifier 1 Identifier 2 Identifier n Identifier n+1 Mask Identifier n+m Mask Identifier Message Received Ctrl Data Identifier #2 Match Message Stored Receive FIFO No Match Found n: number of single identifiers to receive m: number of identifier groups to receive n and m values depend on the configuration of the filters |
