* OS events: Such events are only available after this stage completed and
|
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
|
331 |
* possible that a timeout event occurres 'simultaneously' with
|
332 |
* some other event. This can be caused by several timing issues
|
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
|
337 |
* it is evaluated at the end of each iteration of the loop.
|
338 |
* delays: Depending on the current state, delays are required by SSSP
|
339 |
* for timing of the sequential activation of signals.
