can be used for CAN bus analysis nodes.
changed until “valid reception” is detected, so that the baud rates in the module match (“valid reception” means a
message frame has been received in the CAN protocol layer without occurrence of an error and with an appropriate
ACK between nodes connected to the CAN bus). A valid reception does not require message frames to be stored in a
receive message buffer (data frames) or transmit message buffer (remote frames). The event of valid reception is
indicated by setting the C0CTRL.VALID bit (1).

The CAN module provides a receive-only mode, single-shot mode, and self-test mode to support CAN bus
The receive-only mode is used to monitor receive messages without causing any interference on the CAN bus and
For example, this mode can be used for automatic baud-rate detection. The baud rate in the CAN module is
