38.7.2.1 Filtering Standard or Extended Frames

The “Filter Match” flowchart illustrates the flow of matching a single filter object to the received message in RXMAB.

The filter object can be configured to accept either standard, extended or both frames. If MIDE is clear, both standard and extended frames will be accepted.

If the filter may only accept standard frames, then MIDE must be set and EXIDE must be cleared. If the filter may only accept extended frames, then both MIDE and EXIDE must be set.
