Example 3:
CAN messages with the CAN identifiers 0x123, 0x124, 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.
Set the filter mask:
