14.9.2.1 Filtering Standard or Extended Frames

Figure 14-17 illustrates the flow of matching a single filter object to the received message in the RXMAB.

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

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