||
| 324 | * thus should never occur. However, there is an optional hook

||
| 325 | * to handle such events, nevertheless.
|

| 326 | * CAN events: At least one CAN message was received. Note that this event
|
||
| 327 | * will only fire again if all input buffers have been cleared.
|
||
| 328 | * timeouts: If some module does not support the sequence of there is any
|
||
| 329 | * issue, such a case is detected via timeouts and must be
|
||
| 330 | * handled accordingly (see abort state). In some cases, it is

| 333 | * and is a valid situation. As a result, any other events
|
||
| 334 | * should be handled before the timeout event. If the other
|
||
| 335 | * events are expected and valid, this implementation requires
|
||
| 336 | * the timeout event flag to be cleared explicitely. Otherwise
|
||

|
