Filter Calculation Example 3:
CAN messages with the CAN identifiers 0x123, 0x124, and 0x125, 0x621, and 0x726 are transmitted. The required
filter mask must be determined using an XNOR gate. Other CAN messages that comply with the filter mask are also
received. CAN messages with other CAN identifiers are not received, but forwarded to the next online CAN object.
