    There is not a register called CRCE. If a coming CAN message passes the acceptance filter, the message will be stored into a mailbox. The CAN messages are filtered using an Identifier or a range of identifiers. The mailbox should be configured for receiving message. 

    The CAN bus is a simple architecture where multiple nodes are connected on the same two wired structures (CAN_H and CAN_L). The transmitted data follows the arbitration process, and the signal transmitted is received by every single node. It is on the nodes to decide if they wish to accept or reject any data that is being transmitted to them on the CAN bus.
